I have been looking for a new burner to replace one of my weak ones in my 3 tier setup, and i saw this at costco. http://www.costco.com It is not really what i need, but it seems like a pretty good deal, and if you built a system around 1 or 2 of them, you could do some serious brewing. Maybe two 10 gallons batches at a time, if you could fit 2 kegs on it.
I think I am just going to buy a cheap 55k btu burner for what i need, and the best deal i can find is about $40 at target. Let me know if anyone knows of a better deal.
MOD EDIT: Fixed yer link fer ya.
