I have the
Coleman Roadtrip (I think the LXX version) and I'm less pleased with it than I expected. The scissor stand is fantastic, and I like that I can swap in a grate to use one or both burners as a stove. Set-up and tear-dow/storage is quick and easy.
Where it falls down for me is in the low lid and the fact that I cannot get it to get below about 320º F. It also get dirty inside very easily, causing constant flare-ups.
The previous grill was a ~$40 table-top rig from Wal*Mart; we got years out of that thing and I think I may go back to it. Really.
My dad has two Weber Qs. They seem okay, but if I ever went that route I'd be sure to get the largest model.
