I've had two Camp Chef stoves.  The first had high-power stainless steel burners with tiny holes on the side.  It worked wonderfully but after a few years one of the burners went bad.  The burner was not replaceable.  My current one I've had for 2 or 3 years now and would definitely recommend.  It is the 2 burner (aluminum I think), with holes that point straight up, with the legs that wrap up underneath.  I use it with legs occasionally, but more often on table top.  The build quality seems to be excellent and the stove top space for large pans is wonderful.
