Well, I'm moving past the rental stage and buying my first Upright Bass. It's a 3/4 size kay C1, made in 1938. It's a little bit dinged up(ok, more than a little), but as we all know looks don't make a bass. It's really loud, and has a nice sound. I'm paying $600. It'll need to have the top reglued in the future, but for right now it just needs a few minor adjustments(~$50). I can take some pictures if anyone's interested.
