Sunster, if you're really a Yammy guy, then stick with the 2100 or the Tyros. The 2100 is a fantastic keyboard for the money. The Korg is equally great, but the styles are much more intricate and seem less universal. The Yamahas have a simpler rhythm IMHO and fit more songs easier. I had a Korg and loved it; I now have a 2000 and love it. Apples and pears here; but unless you're looking for a break or change from Yamaha, just move up.
