I have a Yamaha Clarinova, bought it about 5 years ago at around £2500. Pressure keys, everything, very good, but like everything in life, you get what you pay for and it also depends on what you are willing to spend,
But get the best YOU can afford, full keyboard (88 keys)
Easy to use, sounds good, etc, floppy drive on it, the newer ones have USB as well, mine has Midi in and out as well, so can connect it to a whole host of items including the computer.
I have been playing Organ and Piano for over 28 or so years and recently started to learn RAG time music, and gee man,,,,,that aint easy at all. well not for my left hand anyhow!
enjoy and go try and load of different piano's / keyboards, find one that suits you.....
