Moss, if you haven't recorded with a digital stand-alone, any model will probably be confusing at first. One model might seem a bit more confusing than another (partly because it may have more options), but any of them will take some weeks and months of study and experimentation if you're new to this stuff. Like many folks here, I came to digital recording from a Tascam cassette Portastudio and felt rather lost at first. I soon realized, though, that any learning I did at first, even if a bit painful, would help me with digital recording (with any make and model machine) for the rest of my life--really a small price to pay for a lifetime of enjoyment!
Particularly helpful to me were two things:
* A helpful user-support group for the machine I decided to buy--somewhere I could go with the stupidest of questions and still find help. Do some poking around to see how the group looks for any machine you're considering. The Yamaha aw16g forum--and it's a great one--is here:

* Buying a good book on the simplest basics of digital home recording. The best I've read (and worn out) is Home Recording for Musicians-Dummies by Jeff Strong, available at most of the big book retailers. It's a very accessible book, written in a light style, that covers the basics for recording newbies.
Good luck, whatever you decide.
