I think it would depend on what you plan to run with it. If you are not using anything more than a turntable, CD/DVD Player with analog outs, one other analog device and a recording unit, then an RR2150 in good shape will work fine. If you need just one digital input, other than the rather odd USB connector, then it is not really going to work for you.

A/V equipment lasts a long time, so I tend to look at the cost as more of an investment than an expense. I still have a Technics SA-300 that I bought in 1979, and it is still going. The thing that drives purchases now tends to be new requirements on the video end of things.
