How often do you plan to use your grill and what do you plan to use it for? If you can answer that question, it'll help you narrow down your purchase.
I purchased the Home Depot exclusive edition of the
spirit E-210 Webber because I plan to use it as a replacement for my kitchen stove. I like to cook lots of food once or twice a week and when you cook that amount of food, the entire house tends to smell. In addition to that, the Home Depot exclusive version of the Webber comes with a specially designed grill. The grill is interchangeable with other Webber products such as a Wok, Griddle, and a few other things. Basically, it can do everything my Kitchen can do without having to stink up the house.
If you don't plan to use it as often, you can go with some other brand.
