I have, and I couldn’t find any cheap ones (i.e. cheaper than a very good digital piano).
The ones that look cheap in the small ads are generally in poor condition. The vintage ones in good condition are expensive, and new ones are expensive.
A few years ago I was looking at a Schimmel grand for $30,000 (CAD). That's a big purchase, but I could afford it, especially for something I'd use daily for the rest of my life.
A modest house in Toronto is now over $1 million, and appreciates annually as much as my entire annual net income. I will never afford that.
I bet you could get a personal loan for a piano about as easily as you could get one for a car (from your bank, of course, not a car dealership).
