I play this instrument for a living. I've had several basses, worked in music stores that sold and repaired them, etc.
(Upright) Basses can be expensive to set up correctly, and they can be expensive to repair. You MUST start out with a decent intrument. You could go on Ebay and buy a cheap Chinese bass-like-object for about $500 US. DON'T. Read the horror stories at Talkbass of the people that did. Find out how it took $1000 of repair just to get "playable". Don't even consider a purchase unless:
1) You get someone who's been playing a long time that you know and trust to inspect the bass.
2) If you don't have someone, find a bass teacher and take him/her to see it.
3) Or spend an absolute minimum of $1500 on a bass from a WELL RESPECTED luthier. By well-respected, hang out on Talkbass and you'll learn some names. Upton bass, Arnold Schnitzer, Bob Gollihur, just to name a few.
No used basses from people you don't know (unless someone qualified sees it), and no cheap Ebay basses. Seriously. You would likely end up with an instrument that will be near-impossible to play, fall apart, and have no resale value.
If you follow my advice, you will get an instrument you can play for many years, and maybe even sell for more than you paid for it. $1500 - $2500 will get you a decent bass. If you can spend about $3500 US, you can get a much nicer bass. For $6000, you can get an excellent bass.
Let us know how it goes.
