I have a Silver A and dream about finding a Summit at a price I can slip past my wife. In the meantime, the two burner A is performing like a champ! I have it set next to my charcoal burner when cooking in cold weather and anything that comes off the grill goes on the gasser to keep it warm until the trip inside. It's also great for quickly grilling some veggies.
I did have a Gold (but w/out the side burner) which I gave to my fishing buddy and he really likes it.
