I went with the Bayou Classic SQ14. It's inexpensive, seats a keggle on it perfectly, and I've heard it can work just fine for 10 gallon batches. I haven't done 10 gallon batch yet, but it brought 8 gallons to boil in a damn hurry and had to back it down quite a bit for a rolling, under control, boil. I've been quite happy with it.
