Go through this section of the forum and read the threads about digital/electric pianos. You'll find a load of information. Take a good look at the Yamaha P, PF and YDP series as well as the equivalent versions from Roland and Kawai. Definitely, get one with 88 weighted keys. Test every contender in person for a long time before you decide on the one that you like best. The fun starts at about $1,000. Good luck!
