I'm pretty sure you can put a bigsby of some kind on your 'Paul with a very few small modifacations- none really to the body. BUT you're looking at (around) $150. Basicly, the bigsby attatches under your strap button, and you'll want to replace your bridge with a roller bridge. Somebody also makes a trem bar that mounts right where your stop tailpeice now sits. That one is about $200. You'll find both with Stewart MacDonald's Guitar Shop Supply.
