The AW4416 was reviewed in the March 2000 issue of EQ magazine. Also, there are some excellent materials available on Yamaha's web site, including a full-color printable PDF which makes a nice brochure detailing all of the features of the deck.
This one looks like it bears some further looking. My friend has
an AKAI DPS 12 which has great sound quality but not a lot of features or storage.
By the way, I have Cakewalk pro 9 and cool edit pro on my PC and find them to be a huge hassle, which is why I'm investigating the all-in-one digital multitrackers. Unless you have a lot of time to learn (and a PC which is at least in the upper middle in terms of performance) I would not go the PC route. I think you would want a PC that is at least a Pentium III/600 with 128MB RAM and a huge, fast hard drive if you want to go the PC route. The PC would also be good if you are using a lot of sequencers and sampling. For guitar-based pop/rock stuff, IMHO, the digital multitracker is the tool of choice.
You might consider using cool edit pro on the PC as a wave editor and/or mastering software. And, if you want to give your final mixes any kind of wierd or special eq or treatment, cool edit has some neato algorithms. I also use it to clean up wave files generated from mp3's that I download, 'cause sometimes they don't come through clean for whatever reason.
