I've never owned one but I know that they really improved the codec tremendously the last couple of years and the sound is supposed to be quite good now. About the only negative thing I've heard about that particular Yamaha unit was something about the laser getting a bit hot inside them after a while and ruining disks. I don't think that was just a rumour either but the other guys here could probably tell you more about it.
We record with a PC now and to be honest I wish we would have waited till we could've afforded a good stand-alone work station. There's always compatability problems with computer stuff. It just seems like it's always something. It's a never ending battle. You buy a new recording software and suddenly find out your soundcard has issues with it. Then you get another soundcard, it works great, but you still have some bugs with the new software and then you find out that it'll work better with a newer operating system. So you get the new W-XP Pro and then find out your soundcard drivers aren't compatible with XP yet. And then you find out your VIA chipset is.....yada, yada, yada. I ain't really knocking computer recording because it's better sounding and cheaper than a lot of alternatives, but it also has it's drawbacks. I'd much rather have a couple of A-DAT's.
