To be fair, the Norlin era was not a shining example of Gibson's work. Shallow carves, the aforementioned pancake body, abandoning the Standard, introduction of the Nashville bridge, 14lb behemoths, etc etc etc. That said, the fit and finish on the typical Norlin offering is heads and shoulders above its current counterpart, and people love those T-Top pickups these days.
I'd still lean towards picking through the chaff, and grabbing a nice newer sample with the configuration you want, and pocketing the cash, before you get attached to the damn thing. I could probably sell my '78 LPC for enough to get a used R0, maybe a new G0, but I've had the silly thing for 20 years now, and bought it for $400. Plus, ever since I did pots/caps and pickups on it, it sounds dreamy, and it's always been a primo player.
