Hey Pony, sounds like the D1200 is your man. Editing on the PC is a blast and much more fun that doing it on the Korg (though it is possible). If you end up going this rout don't bother getting the CD drive for the D1200 mki I as it will do USB transfer of .wav files. This will save you about 200 USD.

I got my D1200 on ebay and payed ~600 USD for it. That was before the release of the D1200 MK II which is identical to the mk I (minus some blue paint). This will probably force the price of the D1200 down further so in a month or so you should be able to get a MKI for about 4-500.

Best of luck dude !
