You're talkin' about $50 to $75 worth of wood at the local hardware store, then you route it a bit, and TA DAH! Bed wood.
I've seen a variety of kits, the only real difference was the kind of wood they used, for $195 i'd expect the kit to be plan old pine.. which in most cases would have been the wood installed from the factory.
If you want it to last, make sure you treat each board before you put it in.. top, bottom, and sides with a quality sealant.
As far as Chevy Duty is concerned, there have been complaints about them, usually regarding the wrong part being shipped, delayed shipping, or general poor customer service, but as a whole, they seem to be stable enough to get the right stuff eventually.
