Korg D1200 is your man ! You can expand from there.

Check the KorgStudios link in my sig, Im a mod their. They are a great bunch and can get you started.

You can pick up a second hand D1200 for about 4-500 bucks. Dont get the Zoom one you will regret it in 6 months.

I have had both the D1600 and the D1200 and they are both excellent bits of kit.
