I picked my portable gas grille at Lowes last week. Already used it twice. It was mildly costly for such a product, under $50.
I looked for something that is portable, compact, sturdy, collapsable, but big enough for grilling 4 burgers, couple dogs, heating couple corn ears, and used the basic camping fuel/propane tank. I took into consideration the grease which would be left over. Mine has a small drip hole in the base pan, but the base is not toleranced enough to have it drain, or I may have the stands backwards. So repacking requires a little maintenance. Not a big deal, just something to note for use. My grille has the pipe which the regulator screws onto sticks out very little from the overall width. On others the regulator was integral and way out there.
