I have a 6' southern yankee, and I enjoy using it, it does give you nice even temps, and capacity is huge. I found mine used, and picked it up for $1,500. I'd recommend one if you need that kind of capacity. If ya got any other questions , feel free to ask, I'll do my best to answer them. Good luck in your search.
