A A100 for 50$ in working condition? I'd buy it in a heartbeat. Unfortunately there are no deals like that in my area, there's a M3 for 250$, i thought of buying it but decided not to.
What's amazing is it sat for two full days at an estate sale priced at $200. I showed up the second day when everything was half off, and it was still there so I figured by that point nobody wanted it. I offered the estate brokers the $50 after the sale and they accepted. The organ would have probably gone to the dumpster if I hadn't called. Only issues were scratchy drawbars and some missing harmonics here and there which I've since fixed. The finish is living room quality as it sat in the house for nearly 50 years!
Lucky you! I can probably find some L-100 or similar for a 100$, but not an A-100 around here. I'm always looking at the local craigslist (have done some selling/buying/trading myself) but wasn't aware of state sales, i mean, of course i knew they existed, but never thought about looking at them as well. Thanks, i'll be searching for estate sales in my area and who knows what i might find.
Edit : a question, were you able to try it out and make sure everything was working at the estate sale?
