https://thorkitchenparts.com/products/part-number-10201038 Just replaced mine that had the blown out bubble problem with this. Same BTU, same length, and it's a perfect drop in replacement at about half the price as the NXR part (if you can get it). The slot on the mounting tab is wider than the NXR, but all that needs is a small washer. Thor may even have a better design - the ignitor mounts further away from the burner. I suspect that moves the fuel ignition out of the burner tube and may prevent the bubble problem, but time will tell.

One thing not mentioned here: The super susan's require you to have one of those annoying, hinged, bifold doors. You get significantly more storage in a super susan but the trade-off is that awkward door. I just had a regular lazy susan installed because the doors are attached directly to the pie cut-out and spin with the unit. Decide what is most important to you, storage or a rotating door. In my case I knew that hinged door would make me psychologically unstable. The pictures from my cabinet company showed the regular lazy susan with the same awkward hinged door as the super susan, but I asked and it turned out that the revolving door was a no-cost option. I know this thread is old, but the door difference wasn't mentioned here and people do look for info in these old threads.

A "lazy" susan is the one with a center pole. A "super" susan is the one with no center pole and with "turntable" type shelves mounted on stationary shelves. There are pros & cons to both. Pro(s) to both: It's very easy to access whatever is stored in it...everything is in front. All you have to do is rotate the shelves and what you want is right in front of you! If something does fall off (in the cabinets w/out a curved wall, more on that later), it's much easier to get to the item than if you have a blind corner cabinet and something falls off. With a blind corner, you have to reach (if you have very long arms) or crawl into a cabinet that's deep inside a "blind" area. [This reason plus the fact that many of the blind-corner hardware/inserts meant to give you some usable storage do not last is one of the reasons my KD discourages blind corners of any kind.] Granted, you will have to take things off at least one of the shelves with a susan, but you won't be trying to blindly reach deep inside a cabinet that's "recessed" into another one. Note: The pie-cut type cabinet (90-degree angle instead of diagonal front) gives you better access to contents than a diagonal opening. It also gives you more useful floorspace and counter frontage, less of a "closed in" feeling (particularly in small-to-medium size kitchens), and less inaccessible deep corner space. Pro(s) to a lazy susan: Biggest pro, IMHO, is that the walls of cabinets designed specifically for lazy susans follow the contour of the round (or pie-cut) shelves so closely that I'm not sure even a grain of rice could fall off the shelves. Another big pro, again IMHO, is that if you have the pie-cut type, the doors can be attached to the shelves and rotate into the cabinet when you open it. No doors banging the adjoining cabinets...something that can be an issue, especially the doors that are two pieces attached with a piano hinge with the doors flopping about. Pro(s) to a super susan: No center pole in the middle to limit the size of items you can store on a shelf. No center pole to block access to items. Con(s) to a lazy susan: Has a center pole in the middle that limits the size of items you can store on a shelf. The center pole could block access to items. However, all you have to do is rotate the shelf and no more "blocking"! Con(s) to a super susan: Walls are usually not (never?) curved to follow the contour of the round shelves. This is the biggest con, IMHO. Doors cannot be attached to the rotating shelves so the doors must be opened b/f accessing contents, You also have to be careful the doors do not bang into adjoining cabinet(s). Most corner cabinet units/hardware, BTW, cannot easily be retro-fitted after the cabinets and countertop have been installed.

You can, I think, retrofit a different lazy susan, with a pole...and there are some that have pretty good reputations. I don't believe you can do it with a supersusan. I know that my ROTSG (rotten, thieving sack of garbage) GC did not get mine put in before counters were on because he was in a rush to meet that deadline and get a draw from the bank. BUT, he claimed it could still be done because the back side of the cabinet is accessible through the peninsula side and the panel for the back of the peninsula is not yet on. The cabinetmaker intended (before he and the ROTSG disappeared) to unscrew the back of the cabinet, install and put the back panel back on. I think the door to a susan cabinet is not large enough to put the shelf needed in.
