Phil, you shouldn't be so down on electronic keyboards. I bought a Korg N1 keyboard for around £1,000 about 12 years ago - stage quality and superb sounds. It has 88, weighted keys, so touch is important, and I also have a sustain pedal. innumerable piano sounds, from classical concert to honky-tonk. You can amplify the sound with low-cost JBL speakers, or play with earphones, or record directly into digital recorder or computer.

It also has an amazing set of sound banks which, if you're in experimental mode, are quite stimulating - it also has a wide array of orchestral and other instruments which, believe me, are very realistic. You can see it in action here:
