Having anything older than a mid-90's bike is probably going to require quite a bit of wrenching (aka repair/upkeep). Since those are costs you haven't the funds for, the waiting route is probably better unless you come across something.
In the meantime, start looking for gear reviews and getting into the MSF. You could also track prices of the bikes you think might be possible over the next few months to get a feel for what's being asked. Ebay, craigslist, and local news sources will provide the data.
