I own this Turbo Sport
portable infrared grill:
It's a bit spendy at $200, but it's a fantastic piece of kit. It's not your normal gas grill, as it has a ceramic grate with hundreds of tiny pores to vent the super heated flame. It heats up instantly and provides considerably more heat than any gas grill.
It accepts the common portable gas tubes or can be hooked up to the standard bulbous propane tank with an adapter.
It sears fantastically and cooks very very quickly.
Few words of wisdom:
1) Even though it's fairly small, don't cook indoors!
2) On coldish nights, a portable propane canister can freeze to the unit, but I've never had that problem with the full tank.
3) Don't cook with the lid down
I love it. I'd buy it again, heck I might buy another one for higher volume cooking.
