yes, I've been out of the hobby for a while.
the local shop used to carry a lot of stuff from them and they seemed like decent parts. I bought fuel line, a foam air filter, pipe connectors, header gaskets, rims and tires for my buggy that was made by GS and it all seemed like high end stuff.
it looks like they dropped off the face of the earth. I can't find one online store that has their stuff.
