I have the 180 grill and have played with the Slatgrill at Canoecopia. They are not similar machines. The 180 is tiny relative to the slat grill. The Titanium slatgrill is the way to go - just 1 pound but you get what you pay for.

The Arctic Fox grill is nice but no wind screen and it is relatively heavy.

I don't grill much, just boil water so the LittlBug is what I use most of the time.
