Would something like this work?: http://www.homedepot.com/buy/broan-elite-external-900-cfm-blower-for-broan-nutone-range-hoods-332h.html Probably will work (I haven't any idea about the motor interface, or the duct size interface) but the actual flow rate may be a tad low for such a large hood and stove. You probably get what you pay for in these cases. It is always possible to buy and install it, and then at some later date if it proves too wimpy for your cooking style change it. My guess is that it might be too wimpy for anyone who actually intends to make full use of a 48-inch Bluestar. kas

May I ask why you don't want a CC? Assume too much power if that is why you want the RCS over RNB. I'm still between BS & CC. Swim, I know that question wasn't directed at me, but I'll chime in anyway. I was quoted $2550 for a 30" RCS and $4290 for the RNB. Upgrading the burners on the RCS from 15k BTU/hr to 18k is $200 per burner, and upgrading them from 18k to 22k is free. I plan to upgrade two burners, resulting in two 22k, one 15k, one simmer, which should cost just under $3,000. This saves me $1300 over the RNB, and all I really give up is the convection oven. (I probably could put that it myself, too, if I felt it was important enough; they sell the fan on their parts list.) The RCS is just flat-out a good deal. Here is a link that might be useful: Hotrodding an 18k RCS

My Bluster range was just delivered in January 2018 and I too thought I was getting the newest model (RPB304BV2). My serial plate looks suspect at best (the over printing looks counterfeit in my opinion) and reads (RPB304BSS). Internet searches showed the BSS was discontinued in 2011. When I inquired further I was told it must say V2 somewhere in the model #. Please help, I attached a photo of the serial plate, I don't see V2 listed anywhere.

IMO the DW is worth not much I will always suggest a Bosch DW as for the range find out all you can about both and how that works with your cooking style. I have bertazzoni 6 burner all gas rnage one of the burners is a wok burner . I love it but it does not have aself cleaning oven but not a big deal since I amused to commercial kitchens with no self cleaning ovens The range works for me both because I do a lot of wok cooking and I love baking some stuff in a gas oven. I also have double KA all electric wall ovens self cleaning I guess what I am trying to say is get what works for you and how you cook.
