with the oven (crammed against the wall). sorry i dont have any better pictures at the moment

I may be missing something, but if you're putting a circular "shelf" into a rectangular cabinet, i.e. your 33"x36" - the maximum diameter of your circle will be constrained by the smaller of the two dimensions. This will result in lost or unusable space in the cabinet. Better to keep it square for a lazy/super susan. Good old fashioned graph paper and a compass may help visualize and finalize your dimensions. There's nearly a full square foot of space differential (per shelf) between using a 28" diameter shelf vs a 32" diameter shelf. With two levels in the cabinet, that's a lot of storage space.

ShaggyDogs - can you do a 36"x33" corner susan? It will give you a bigger opening - that's the biggest limiting factor in a 33"x33" corner susan. Corner susans can be very useful. They're great for pot & pan storage - especially if you don't have drawers for them. They're also great for small appliances. Everything is always in front. You just rotate the shelf/shelves until the item you want is in front - then easily lift it out! I loved the one in our old Kitchen. We stored all our pots & pans, colanders, and large serving pieces in one 36"x36" corner susan - it was a lazy susan (pole down the center) with the doors attached to the shelves so they rotated into the cabinet when it was open. Blind corner cabinets are useless without swing outs or roll out tray shelves (ROTS) You can't store anything in front of the ROTS b/c it needs to be clear in front of them to pull them out. Swing outs can be problematical - especially if something falls off the shelves in the interior - you have to send a small child inside to retrieve the item and you cannot close it until it's retrieved! My KD demonstrated a couple of different models for us - she said most people come back complaining about the swing outs so she moves heaven and earth to not use a blind corner! My MIL has upper and base blind corners (no ROTS or swing out) and she says they're a waste b/c it's too difficult to get into them - she doesn't store anything in the "blind" areas. You may be better off voiding out the corner if the opening is too small to be useful on a 33"x33"....or consider corner drawers, but they will probably be very expensive.

Lisa - two KD people that I have spoken to said that the voided corner does not provide wider drawers on either side. What am I missing? Nothing as far as I can tell because what they are telling you makes no sense to me at all. If you don't give up 12" of linear space to a Susan, you gain 9" of drawer width (3" goes to spacer at corner). I considered adding a BCC to my sink corner (didn't have space on sink side to do corner Susan) but opted not to because a) it wasn't the right kind of storage for that corner and b) a drawer base was cheaper storage than a BCC. Here's my corner. Drawers & trash pull-outs open. If I had done a BCC, I would have lost the bank of drawers on the right. If I'd had room for a corner Susan, I would have lost 27" of much needed drawer storage. The few items that I would have been able to store in a BCC (ditto for a corner Susan) ended up in a a single drawer in a much roomier cab next to my wall oven. I use the items in the drawers in my prep zone much more regularly than the items I use in the drawer by my oven. A few extra steps now and then is a much better option than extra steps several times a day, IMO. Look at the whole picture when it comes to storage. What you decide for one area affects storage in another. It's a domino effect, IME.
