Also, buying bits off Ebay isn't necessarily the cheapest way. Often a body will sell for around the same price as a whole bass. Might be best off scoping a cheap Squire, SX or other solid wood reasonable rep cheapy and resculpting it for your needs. If you want the personal touch, without the finding the bits don't fit, get a kit, hit up ebay for some random upgrade parts as they come cheap, pass the drying and sanding time that way. There are plenty of bridges for not much on ebay and my experience of them has been good, I like the coutour ones, as long as the is enough grub screws, it should all lock together and you can adjust the action and intonation to suit. If you are local to Bristol, I'll gladly give a hand or pointer.
