A word for standalones...
Depending on the $$$ you have, and other things, I'd keep a standalone HD in mind. PC's are great, but will your PC be configured to able to handle quality audio without freezing/crashing? Can you have a PC configured specifically for audio and not load on other non-audio programs? Then great!
Also, will you be happy recording in one location? Non-laptop PC's are not something you want to lug around on location.
However, a portable DAW (8 or 16 track Fostex, Korg, Tascam, Yamaha) is VERY portable and will allow you to produce a finished CD without leaving the box. By and large, DAW's do not have software compatibility issues and their components have been selected from the get-go to be ideal for audio. Price wise, a Fostex VF80CDR goes for $699. and the VF160CDR (which will record 8 tracks at once, 16 through an ADAT interface) goes for $899. These are VERY stable/portable units that will yield great results. Just a thought for consideration...
