I'm off the Pocket Rocket, gave one away but kept one to use in my office with a kettle for afternoon espresso.
I really like the SOTO Amicus. SOTO's build quality is second to none and it has the recessed burner of the Windmaster but is cheaper and has a better folding pot stand system with 4 arms.
I tried 2 of the Snow Peak Litemax and returned them both. I suspect the regulators as one would gradually lose pressure no matter how high I had it turned up and I would have to remove it and let it cool before it would run again. and the second one could not be opened all the way up or the flame would shoot out so hard it would blow itself out...
