That looks a bit like a newer version of my old one - I had a Yamaha PSR-280, I don't think they make them any more.
That's ok.

I don't think I've heard any of those!

I don't play classical music on the keyboard, though - I mostly play classical music on the violin, so for a change I tend to play rock or pop tunes on the keyboard.
Thanks! That's fair enough about the weighted keys - the K2000 does have velocity sensitive keys, but I guess it's not quite the same. I'm actually finding the keys on this quite hard to get used to - I never played with the "touch" setting on the 280 because it wasn't very good (you really had to bang on the keys to make a sound unless you turned the volume right up), so now I'm used to all notes being at the same pitch regardless of how hard you're hitting the keys.
