You wanna lick charcoal or just flip a switch wait 2 minutes and go.

Wal-Mart grills are generally crap, if you want gas thats going to last
go for one what has cast iron or brass burners. Make sure that the
grills arent just thin stamped steel either. If you dont want to
spend the money on a good gas webber, go for a sears (kenmore) grill.
Some of the higher end ones (200+) are real nice and i'm real satified
with the one I bought from them.
