Hercules Stands HCGS-200B

Pretty stable for a travel stand: it's obviously not as stable as heavier/bigger ones but it can take a hit or two acutally (I pushed my guitar a few times to see what would happen and it withstood all the hits). It grips strongly to the floor because of its design: the whole legs are long contact points. 4 stars for stability because it's very stable for a travel stand but not stable enough compared to non-travel stands.
It's handy that it can support both electric and acoustic, and the two options are effordlessly interchangeable. It's made from very flexible plastic though, so it wobbles quite a bit but that doesn't really make it any less stable, it still feels solid.
4 stars for quality because mine is a bit uneven: without any weight on top of it, one of the legs doesn't touch the ground (when it supports a guitar it does, so it's not really a problem, but still gives it a cheap look/feel).
It's quite low so you need angled jacks for guitars with endpin mounted jacks. I didn't try it with Les Paul style jack locations, but just by eyeballing it I assume it would work with non-angled jacks.

Overall a very solid choice for a travel stand. The trick with these is using them in non-busy stages or rehearsals. In places with more movement (or around big dogs and children...) you want sturdier and thus less portable options.

PROS:
Very portable, small and light.
Stable as far as travel stands go.
Cheap.

CONS:
Bad quality control.
Unstable for busy environments.
