I'd listen to Teal.

Thanks! Don't worry about repeating yourself - I'm glad to have the suggestions. I had no idea. I'll call Rob and ask him about the manufacturer, then I'll call a pro. If it's not worth messing with, I'll donate it to Goodwill or something similar.

...what Teal said.

Love ya, but like, with cars, it is always nice to know who made it. Tell me who made it and I'll tell you if you have a winner or just something to bang on. Ask a piano technician (or, as you say, tuner) to check it out and tell you if it has any major problems and what it will cost to fix them. If it is worth working on, but the technician has to do the work in his shop, then the fine tuning still has to be done after it is delivered to your house. Bottom line, you can only check it out yourself if it is in tune and has no problems and then you'll think, oh, it sounds right. An out of tune piano can't be judged by a novice. As for quality of tone, you can play every key top to bottom, black and white and listen to each one and when you hear the tone of one you like, that is the way the piano will sound as a whole when it is fixed. But if no key has a good tone, then it's iffy. Who made it? Sorry to repeat myself, but that's the whole story, like if you were buying a Jeep or a Mercedes.
