Right now I have a gas BBQ and a Weber Charcoal grill, I haven't used the gas grill in 4 or 5 years. I got this Weber when GI Joe's was closing stores in the area a couple of years ago for $85. I saw one at Lowe's the other day for $335. It's my favorite grill to date, by far. It's big enough to smoke a 12lb Turkey and WOW, does it taste good.

A friend has a Traeger that is awesome. Very versatile and built like a tank. When I have to replace the Weber, I'll probably go with this one.

However, I stumbled across this the other day and I just might build one for the hell of it.

It looks like it can do everything I'd like, at a much small price tag than anything else I've seen.
I guess it depends on how you'll use it. If you're just going to flame and plate, I think the Weber is the way to go. If you like the low and slow method, the Traeger or a Little Green Egg is the way to go.
I don't care for gas grills, they just don't seem to be as versatile as Charcoal grills. I use only lump charcoal, none of that Kingsford crap. Home Depot sells a 'Cowboy Charcoal' that I really like and use a lot. Adds a nice smokey flavor, but not a heavy smoke taste.
