itic welcome to the board.
The Sierra Charcoal grill from Williams Sonoma looks a lot like the Char-Broil Santa Fe - 491 Charcoal Grill. Maybe an owner of one of those could help shed some light as well. Next time you look at the grill ask how easy it is to clean out the ash. I like the 532-sq.-in. cast-iron grilling surface!
The Char Griller Super Smoker has gained great popularity around here lately.
Unfortunately, I haven't either unit to beof much help. Good luck finding your new grill and hope you'll stick around.
