As long as the Playfield is semi decent, get it for $400. Could even try and bargain down $50 or so.
It would be a very good first pin to have and to learn on, do some repairs, rebuilds, etc.
If you do get it, download the User/Service manual, any pinwiki System 11 guides, Clay's guide, if you can find it, and any other useful info.
Any questions or how-to, just post here.
Learn the basics, removing the glass, replacing bulbs, checking connections, using a DMM, etc.
Space Station would be a good deal and start.
