Yamaha keyboards - HELP!!!

[MacUsers]

Hi,
I’m just going to buy an electronic keyboard to use with GarageBand and I’m fancy buying Yamaha PSR K1 or Yamaha ZE 250i (I just don’t like M-Audio and I like one with buit-in speakers.) Any idea whether they (either one) are compatible or not? Dose anybody has any experience using one of them? Do I need to install any driver for them?

Help/suggestions are truly appreciated. Thanks in advance.

Buy a large keyboard, so you can concentrate on the music instead of changing parameters, capable of splitting regions preferably, thus defining different sounds in various regions, now play... and get heard, while you're still alive
