Sounds like a deal to me! A good BS book might be in order - Dugginske's gets good reviews. It'll help you tune the thing up and assess what you've got.
They're pretty simple tools, so if it's got a cast frame and table it'll probably do the deed. Look for signs of balancing on the wheels (weights or material removed), which is good. If the frame allows for a riser kit that's good, too. It appears many riser kits are interchangeable between manufacturers.
