I'm looking to do this without spending alot.
I've heard these words before! As for the cabinet.... you never really told us what you wanted to do with it. You wanting to restore it to Primal Rage? You looking to mame it?
The thing I remembered about the only Primal Rage I ever saw in the wild was it had a big CP and huge monitor. (seemed huge at the time).
Fair shape:
If you plan on mameing it - it needs to be solid with no water damage. Anything else is a bonus: coin door, marquee retainer, cp latches, controls, marquee, etc.
If you plan on restoring it -
You'll be looking for as much artwork as possible in good shape, good controls, original cabinet (if it came in a dedicated cabinet).
Price can be all over the place. I wouldn't pay too much for a non-popular game that your not sure if it even works. Does it play blind? Without knowing where you live, or if the game works and what controls it comes with. I'd say $100ish sounds good if it's nice and solid.
