A little advice please. Junk or not?

I've been kind of looking for something to maybe get started with a little recording. I have a GNX3 here that I practice with and it has s/pdif outs and I was thinking this may be the easiest way to connect to my pc.
This seems ok and entry level but I really dont know.
