definitely a weber three burner, it's called genisis series something, they update them every couple of years. i've had mine since '95 and i've only had to replace the flavorizer bars once, back in '03.
i live in the northeast and use it year round, at least two to three times a week. it's great direct or indirect grilling.
in addition, the best grill book i've ever gotten is "How to Grill" by Steven Raichlen. got it two years ago, and have done over half the recipes. pages are falling out, and sauce and sh*t all over it, but it's got the best recipes, and simple too.
grill's around 450-500$ but worth every penny.
