Direct Tools Outlet has the propane powered portable camping grill, SToK Gridiron (model STG1150HD) for $99 shipped. This same grill is available at Home Depot for $160 [homedepot.com]
From the manufacturer's website:
The SToK GRIDIRON portable gas grill is a beast on and off the field. It's perfect for grilling on the go at outings like camping, tailgating, picnics and more.
This grill features the SToK Grilling Insert System, like all other SToK Grills, and comes with the SToK Cast-Iron Grill Grate Insert.

I'm assuming this is a reputable dealer since the manufacturer lists them as sellers of the product.
