I say either get it fixed or buy a new one. If it sounds good you will enjoy it so much more therefore you will practice it so much more. I did the same thing, bought a brand new soprano at a yard sale really cheap, messed around for a while then paid a local luthier to fix it up. It cost more in the end then buying a new one with a set up. I gave the fixed one to my grandaughter, then I missed playing it ( and I stink, but I still love it) so I got one all set up from HMS. What a difference!! I practice everyday because it sounds like its supposed too! Good luck.
