Hi ckreef, thanks for your input, very interesting. I had seen a Santa Maria grill, but hadn't paid it much attention. I think it seems like too much hard work for me, at least for now with 3 young kids and pretty hectic job. I'll just have to settle for a KK.
I really don't have that much room, and so to some degree having one BBQ, at least of reasonable size, is probably all I can handle. As mentioned, I have a 4 burner Weber gas, but I'd consider selling that and maybe even getting a smaller open griddle for when I just need to cook sausages or in a real hurry. ( or maybe a back up if I run out of charcoal, which isn't available where I am).
And, I just updated my order to the 32" So probably won't be buying any other BBQs any time soon.
