As a guy who has been married to a piano teacher for decades, I would suggest looking at the highest quality Yamaha that fits in that price range. I’m willing too say you can’t go wrong with Yamaha.
Over the years we have purchased 4 Yamaha pianos that run the gamut and are all still in service.
The cheapest was around 500 (some years back), and it still works fine in the school.
The next cheapest was about 600 or 700, and would be excellent for anyone–it is my wife’s “play quietly in the bedroom with headphones” piano.
The third was an electronic baby grand for our church, somewhere in the 5-7K range.
Finally, my wife’s baby grand piano was somewhere around 16k.
The first two are perfect for pianists on a budget, young and old.
Go to the store and see what the real prices are–the MSRP for Yamaha is not what you pay. For example, that electronic baby grand had an MSRP that was a few thousand higher than what we actually paid for it.
