If you are looking in the luxury class BBQ I would go with FireMagic.

FireMagic uses cast SS burners 1/4 inch thick. They use 304SS for the body and higher grade 316SS for the burners.

Cal-Flame has very thick cast SS burners but their stuff is made in China while Firemagic is made in Southern California. If I was shopping in this class I would definetly get USA made.

If you don't want to spend this kind of money then I would definetly get Weber. Look through the link below and scrowl down. It shows pictures of different brand of buners cutout.

BTW American Outdoor Grills is a slightly cheaper brand from Firemagic. Not quite the BTUs,bells and whitsles,and no 316SS.

Take a look at this site. They have a lot of videos explaining all their grills.

Those of us who grew up in the pine forests of east Texas shudder ever so slightly when we hear outdoor cooking referred to as "barbecue," but I'll overcome that and say...

I too have heard excellent things about FireMagic (but only word of mouth; I haven't cooked with it).

I love my tec- all infra red, full heat in about 2 minutes.
