I don't know what your criteria are, but if you have a computer already you can just by a USB midi keyboard – probably in the range of £50-100 new. ie, if you had a Mac, you have Garage Band, all you need is a midi-USB keyboard to access all the synthesised instruments. The pianos available on Garage Band are great.
I have not tried any of them, but there are even midi synthesisers available for Android phones (iPhone too), you just need to figure out how to hook them up to the keyboard (and probably some speakers).
