I bought a press from local Craigslist add. The guy had no idea the "jig" was for bowling... He told me that he picked it up at an estate sale and had intended to use it as a regular drill, but then wanted adjustable "table" with respect to height. I've had it for a little while now, went through the whole thing, made sure everything was lubricated, adjusted, zeroed out etc. It works pretty well for the basic stuff. I'm now starting to look for a mill type machine to get a little better precision, drill ovals, etc.
I'd suggest keeping an eye out in your local area for something to pop up for sale. Usually these are at a great price!
