Thanks for the input here, I really wanted the KAB6 but it looked like it sits a little high for a converted keg. I saw this thread about people modifying the KAB4 for the burner height:

Money is not really an issue here but I was more worried about boil time. I know that the SQ14 is everyone's favorite for 5 gallons, but for 10 I've been reading it takes a little longer than I'd like. (Or I could just take my time
)
I would've went with a stainless blichmann but their waiting list is 3+ weeks at the moment.
I'm starting to think I'll buy one of each and compare while I brew. That way if I'm tired of waiting for something to get up to temp I'll just blast it with the KAB6 and save gas with the SQ-14.
