I have a large enough gift card for Home Depot that I'd like to purchase a nice BBQ. I already have a natural gas line, so I'll be going this route, and I have to buy it at Home Depot, since I have the gift card.
I'm wondering everyone's thoughts on Weber's vs. Vermont Castings, I plan on keeping this Q for a while.
Here are the models I'm looking at

Vermont Castings VM508SN
I like it as it feels quite solid, 4 burner and infrared rotisserie included.

Vermont Castings VM450SSNC
Almost the same, I like the look better if that counts for anything, but no rotisserie or marinating/beer station, not sure if I'd use it anyways. Is there much difference using a bbq with a Infrared element vs. using the regular burners?

Weber Genesis S-320
Nice looking Q, only 3 burners, heating elements go horizontally across the bbq, not vertically like most are used to. No rotisserie/infrared. Dial controls are not on the front, but on the side. Seems like it would get in the way and takes away from work space. Also the most expensive.

Weber Genesis E-320
Similar to S-320, but porcelain grills and of course painted, not stainless steel exterior.

I'm sure they are all great BBQ's, but can someone comment on their experiences with any of the above models, or why they choose a Weber or Vermont Castings?
