Speaking to the chaps down at Bruce Millers is a good bet, even if you don't buy from them. I got my digital piano couple years ago after checking it out from Bruce Millers, then buying it from Denmark (or at least my mum did as it was a present, and it could be guaranteed quicker from Denmark than anywhere in Scotland...bizzarre yes). But mines a Casio px-320, which is a digital piano, but can also do everything a keyboard would also do. It cost just on the 500 mark. And its full size, weighted and all such piano stuff and connectable to a computer. Really, just have a chat with the guys in the shops, say what you're after, price range and all that, and they'll be able to point you in the right direction. Also, I live in a flat, top floor, and I don't bother anyone with playing. Just in my oppinion, digital piano is the much better idea than a keyboard.
