Peter, try to find a grill with tube burners - they'll last longer than the "H" style. (OR any type that is a clamshell with the crimped outer ring) Also, try to find one that doesn't use briquettes or lava rocks. You'll have fewer uncontrolled flare-ups.
Up here in Canada, a really well built Q is the Napoleon. Not sure about dealers in CA, though. Some have a rear burner for rotising, as well as a smoker tube option. Most also have the option of a Charcoal Tray. Pretty slick - light the charcoal with the gas/propane - when the charcoal is up to temp, shut the gas off and you're good to go.
I have the Prestige II PT450RB with the blue lid and just love it.

*Side note - at your price point, you will probably be looking at their "Ultra Chef" line. They start at $399 Cdn.
