What sort of music do you generally play on it?
Heh, Estonias have higher and higher reputations these days since the business was taken over by Indrek Laul in 1995 and he started to work on making a world-class brand out of them. They are known at least here in the US as a tremendous value with the European characteristic of a more fundamental tone rather than the NYC Steinway overtone-heavier one. I actually have never played an Estonia. I've just read about them, but their current reputation makes me want to try one and see.
I love the Steinway with a great, great love, but if I found something of comparable (or better?) value and could get back some extra money to put away, I would.
