www.basstabarchive.com is another good site for bass tabs, went out of action for about a year but looks like it's getting updates again now, best thing about it is that they only keep one version of tab for each song so you don't have to go hunting through to find the correct version, which can be hard if you're just starting out. they must check all submitted tab is correct first or have the same people right it each time who they know will be correct or something.
i've still got my first bass, it's a fretless yamaha, and i love it, i took my guitar playing mate with me (who happened to play bass in a band at the time) afterall it was after playing his that i decided i wanted to invest and just said, look i've got £300 to spend, £400 if i push it, which would you choose?
i had my eyes on the £400 cool looking blue oxbow (or something like that) of course and we tried them all, i'm so glad i took his advice, just wish they had it in the natural wood colour (rather than black) then the fretted version they had there. but this has a really nice sound and most importantly, it's light as a feather!!! it wasn't until i played his again (and hated it) that i realised how nice it was.
a word of caution though : BUYING INSTRUMENTS IS ADDICTIVE, haha, well for me at least
