Where to get a cheap but good P-Bass/J-Bass neck?

I'd like to replace the neck on my Paranormal Jazz Bass with one that has a dark fingerboard and block inlays, but all of the replacement necks I see cost as much as the bass itself did. I see plenty of cheap ones on places like eBay, but I don't really trust those. Anyone know where I can get a good quality neck of this type? Brand does not matter, as long as it lasts. TIA.
