If you want to experiment with a cheap experimental/alternative bass, this company may be what you're looking for. I bought a shortscale SX jazz bass type i've set up as piccolobass - See it in action here -, and a fretless SX jazz bass type - See it in action here. Of course you can buy more expensive basses but with price tags from 100 - 140$, you can afford to but that experimental model - next time ill probably get an 8 string(!), they're really great for the price.
