I recently picked up one of these for a song and am not sure if I want to keep it or sell it. It has the smoker option installed on it. I have not been able to find any used ones on the internet. Do any of you have experience with this type of smoker? If I were to sell it, what should I expect to get out of it? It looks like new ones are going for around $10K. The link below has pictures of this type of unit. Thanks for your input!
