Also, I think the idea to buy the burner/pot separate is a good one. Looking around there are some deals to have. Certainly keeps it cheaper than I was thinking.
The SP-10 puts out a lot more heat, but is louder and uses more fuel. The SQ-14 stand will hold a keggle without modification, where the SP-10 stand needs to be modified or have a grate added to the top. Either stand is good for standard stock pots. They're both great burners, and are usually priced about the same.
There are too many factors to be able to accurately estimate what your fuel usage will be. For a frame of reference, when I used an SP-10 I got ~4.5 batches out of a 20# tank (filled full, not the 3/4 full tanks you get when you swap). That was doing 10 gal all grain batches, heating strike and sparge water, and typically boiling for 60-75 min.
