Alright, I figure it's 4 in the morning so why not throw in my two cents?
Here's my take on the situation. Time and time again I have contemplated the purchase of a digital multritrack machine. I figured that it would be real convinient for spot recording, as oppose to carrying a whole bunch of gear to make up a similar system.
Now let's pretend that portability is key in this situation, since I believe enough people before me have established that for a non-mobile setup, a computer based system that is appropriately setup would be the best way to go. So, with that in mind...
Personally, the only digital multitrack that I would even consider buying would be the VS2000, or similar model, by Roland that allows for expansion cards to be added to have modern plug-ins that are used commonly on computer based system, sure as Antares Auto-Tune. Even with that in mind though, these systems tend to come with relatively small hard drives which leaves them to only be able to record so many songs before you have to dump all the data off of them...I do believe they can be synced up with a computer for purposes of dumping data.
The next thing that I would consider is the fact that typically the preamps on these units really are under par. Now while it is true that a professional with worse gear can make a better sounding recording and mix than an amatuer with the best equipment, I'm sure you would agree it's always nice to have better gear. With that in mind, a company such as MOTU has products that are catered nicely for portability, such as the 828MKII or the Traveler. The preamps at least on the 828, don't know much about the Traveler, are actually pretty decent pre's, though I'll admit there are only two on there, though the 896HD would be another option, not to mention other companies making Firewire interfaces. So this would allow you to connect to a laptop fairly easily. From that point, pick any software you want, and you have what I feel is a more user friendly interface when it comes to actual editing.
BTW, correct me if I'm wrong, but I assume you are using a desktop and that mobility is not really the biggest of concerns, and so as stated above, I really feel that you will get more out of a computer based system. I also agree with Joe Nerve (nice to see you again Joe) that the more time you put into a system the better you will be no matter which way you turn. But keep in mind also that a computer based system will also allow for more interchangability between other machines to have professionals look at it and help you out, or have people you know, or I'm sure some people on the board here wouldn't mind helping you out and looking at your stuff after you track everything helping you with the mix down.
I don't know if any of what I have just said has made any valuable sense to you, but hopefully it has.
