I used to use a Char-Broil Tru Infrared grill. Mine was a 3 burner though.
Honestly, I'm not a fan. The grill always ran hot. I don't think I ever was able to get it below 450 degrees. The grill plates discolored so badly from the heat, they looked rusted too. To Char Broil's credit, they never actually warped though.

You could doubtless do worse with a cheap grill sold at Walmart, BUT if you can afford it, I'd really urge you to get a Weber gas grill. They're about the best of the big brands out there. More costly, but you get what you pay for. My parents left their's out on their deck (they live right on the snow line in the mountains) and it still lasted them 10 years.
