Both the 2000 and the 2100 have harmonizers, the 2100 has twice the user memory of the 2000, a few more voices and styles, but other than that there is not a lot of difference between the two. Naturally, the 2000 is now a discontinued model, therefore, you'll find them at a really good price as closeouts. By the time the 3000 comes to the U.S., July probably, the 2100 will also be history as well and the price should begin falling on that model.

Regardless of which keyboard you decide upon, if you're going to be performing in front of an audience, figure on eventually hooking up to a laptop computer, especially if you'll be using midi files and karoke files, both of which are excellent tools. The size and quality of the laptop screen will allow you to view the lyrics and screen selections of other devices much better than the keyboard's screen. Neither, unfortunately, will provide a good view outdoors--keep this in mind when booking jobs. It's a real problem that the keyboard/music industry never seems to want to address, probably because such a small percentage of their consumers are professional performers, and only a fraction of those perform outdoors.

Good Luck,

Gary
