I've used a Weber Q for years. I love it except that the holes in the burner get clogged up with drips and droppings from what I'm cooking. I used a kit from Torjik to convert it to low pressure from the camper:

Grillbilly Rebel and have been pretty happy with it. It has covers over the burners that protect them from drips and whatnot. But at the cost of flare ups. After using it for a couple of weeks, I haven't decided which I prefer. But this grill is really nice and the regulator would twist out really easily.
