I've got a Black Olive charcoal grill (similar to a BGE and Primo). One of the reasons I bought it is that they also make a pellet grill and the charcoal grill is convertible to pellet feed (in case I ever get tired of charcoal). You might look at their pellet grill - as far as I'm concerned it's the best of "both worlds" (pellet-fed convenience and great heat retention/efficiency of the ceramic grills):

You might also look at Green Mountain Grills - they have relatively heavy construction and seem very stout compared to a Traeger:
