If you're looking for a hot replacement for your PRS, check out the Tremonti PRS pickups (not the SE ones, obviously). They're, in my personal opinion, the best pickups that PRS makes. Also "Bare Knuckles" pickups have some pretty nice stuff. They're kind of expensive since they're a UK brand. They haven't caught on in the States yet but it shouldn't take long.
