I know some-one who bought a piano on ebay (don't know how much they paid, but I guess that it wasn't very much) and it proved to be a disaster. I was teaching the child of the family, and my piano tuner went to look at the piano to see what could be done for it, but apparently it was beyond repair. (The family didn't know that I knew the piano tuner and got his version of events!) A salutary lesson perhaps.
Anecdotal evidence is no basis for sound judgements.
My grandfather lived into his late eighties, but it wasn't because of the health benefits of pork pies, or the teaspoon of salt he poured on every meal, or the 40 Woodbine untipped that he smoked every day.
What we need are some statistics, then you can make some senssible judgements about risk/benefits. What are selling prices on eBay relative to other sources, proportion of dodgy items, etc. Relative trustworthiness of private sellers v. commercial outlets, etc. I don't know anywhere that provides this sort of analysis.
But a Yamaha C3 for £1000? The case, metal frame and keys have to be worth that, even if the sound board, wrest plank, felts, and half the strings are k*******d.
