Their higher end stuff is great. Their cheap stuff is complete crap, as expected for that kind of price.
People like their custom stuff. They feel special because they had to wait 6 months for their limited edition holster. They don't like that you can get a holster of similar quality without the wait and a slightly smaller price from your local gun store. Makes them feel less special.
ETA: I'm one of the guys who (not currently, though) likes their custom, limited edition stuff. I think Sparks, Rosen, etc. make awesome stuff, and it's nice to have hand made things. But I do own a few Galco and Desantis items.
