His website is kinda slow, but that's about the only downfall. I purchased an Ultra Carry and a Grand Raptor from him and he also did my CHL class. He's good people.

I have to add, though, that Spectre did recently jack around a friend of mine on some night sights he'd purchased along with a new Kimber.
