Pat,
I just answered your email but now I see the post. I didn't realize you wanted a 76 note keyboard when I recommended the Yamaha PSR3000 and the EXR7 Roland which does have 76 keys.
I still think the EXR7 is very similar in sounds and styles to your EM2000 which only has 61 keys. The sequencer is 16 tracks on the EXR7 and you can load your EM2000 styles you like right into the EXR7 or play them directly from the floppy disk. This keyboard is less then your budget but would be a good choice if you don't want to leave the Roland brand and stay in your budget.
