I use the GSI Minimalist and love it!
There is a small weight penalty. It's 1.8 ounces heavier than my equivalent MLD 850ml pot kit. But for that you get:
* A very sturdy 600ml non-stick anodized aluminum pot (this thing is not going to dent short of repeatedly beating it with a rock)
* A nice fitted neoprene cozy for keeping stuff warm
* A triple purpose lid that actually works well (strainer,sippie lid for the morning coffee, and tight fitting storage lid)
* A functional lightweight pot gripper
My entire Fancee Feast cook kit and 2 ounces of alchol fit right inside of it. The pot, cozy, lid, and pot gripper weigh 6.0 ounces on my scale.
The cozy and lid make this an especially nice kit for coffee drinkers.
Ditch the provided spork though. It's pretty much useless.
