+1 to the cheap-o on craigslist. get a squier, put that nice rosewood neck on it, you seem like a gear-head so i wouldn't doubt that you might have a nice set up pickups sitting around, and then go to town on it! sure, it won't be that badass lava p-bass, but it'll be something for a while. the starter squier p-basses go for REALLY cheap. i know because i've done some shopping around. i have a p-bass neck that would love to find itself a body sometime soon.
