I went with the Ignik, and I added glass chi-chi fire beads to it, to soften the flame profile and look cool.
I like it for being small, self-contained in that I can store the gas hose and lighter inside the box even with the fire beads in there, easy to use and pretty --in that the sides are open/vented. I use it either with a little 5lb bottle I bought at Costco (the gauges on these are wonky) or my larger "bbq" propane that's sometimes hauled for the two-burner Coleman. The ignik was $100 at REI with a discount coupon.
The shortcomings of the Ignik, in my experience, is that the valve fitting juts off the long side/back of the ammo can and is somewhat "exposed". Pack carefully. Also, y'ain't gonna cook marshmallows over it very well. It does throw some nice heat and has become a staple for our quick runs for sunset over the beach or camping where open fire isn't allowed.
