I posted this in the main forum but dont know how to move it. Im a novice with a lead on 2 GC1's. In our phone conversation with the buyer he stated one as good and one as very good. One is set up and one is disassembled. below is the one set up. I can get these real cheap, just wondering ways to identify models and anything to look for in condition that would suggest to pass on them. I have had a few helpful responses with other post but one suggested asking in this section. Any help and feedback would be greatly appreciated.
