we have the all gas version, and it's retail is $3799, so the dual fuel is more than that. I priced it but can't remember how much $4500 maybe?? $1650 is a good deal, depending on how old it is, and how used it is??

Are you considering the all gas or dual fuel?

I went with the Thermador. I was pulling the trigger on the JennAir, but they said the model I wanted was still in production and several weeks out from arrival. I was offered a great deal on the floor model Thermador above and decided to go that direction. I had a few issues the first few weeks with the Thermador, but customer service was great and they handled all repairs without question and very quickly. Beyond that, I’ve been using it since October and have really loved it. I know that doesn’t help with your situation of deciding on the JennAir offer you received, but my research on the JennAir seemed very positive.

@Mark Walchle I wish I could find the post I have been following for a couple of years about BlueStar's ignition and explosion problems, but I cannot locate it at the moment so will try to summarize. Basically what has happened is that many of the new BlueStar stoves are having dangerous problems with ignition and gas escaping and exploding to various degrees. These problems are persisting after multiple repair visits. BlueStar is reportedly aware of the problem and has done nothing to fix it in production. One woman commenting in the thread posted a photo of 3rd degree burns her husband got on his arms from a BlueStar stove. You can search the Houzz archives for more information.
