The factory has been doing the replica thing for years. From the staggered height of the polepieces, the cloth wiring on the entire wiring circuit, to the different colored base on the pick-ups.
The custom shop takes it one step further, and they'll age the finish with the cracked finish (checking, chequing? sp?) and all. But as nice as they look, half of the fun for me is making the neck all dirty yourself.
The vintage market is through the roof. A guitar these days, can fetch over 60k....it's just a plank of wood with some metal!!! Sheesh!
