If the price is right, it's still very useful. Maybe not the greatest mic pres/conversion in the world by todays standards, but for plugging in a bunch of synths or something it would be fine. I'm still using a Yamaha 01V which is very similar that I bought 15 years ago. I only use it to plug in a bunch of my hardware synths - outputted through SPDIF to my RME. It's fine for that. Dead quiet, which is nice. I retired my analog board 'cause it wasn't dead quiet anymore. The analog board was more forgiving with respect to peak levels - digital isn't forgivng at all, plus it did impart a little something to the overall sound - whereas the Yamaha does not.

Definitely see if you can locate some YGDAI(?) cards for cheap. Waves even provided their plug-ins for one. I still have my old AW4416, which came after the O2R, and it still works like new. The only thing I worry about is the belts for the motorized faders breaking. Best of luck!
