I have owned the Korg D1200 and D1600 and Korg make good kit. The D1200 is brilliant and much better / more versatile / bigger bang for your buck than the PRX4 (but not as portable) and Id recommend it to anyone. You can pick one up second hand for about 4-500 bucks on eBay (get the mkI not the MK II, the difference is price tag and a paint job !). If you decide to go the computer rout later on, you can export tracks via a USB port.
Id not go the computer rout as too many things can go wrong. Although computer recording is more versatile and has a better interface than the D1200 etc, with the stand alones you don't have to worry about:
Stability,
system resources running out,
plug-ins,
plug in compatibility,
system configuration,
latency,
access to inputs and outputs,
non-standard interfaces,
crappy pre amps,
crappy ADA conversion...
the list goes on.
Great if you know computers inside out but bad if you don't.
