Rotel RCD-1070 replacement

I bought it new about 10 years ago, but haven't used it on a regular basis. On several occasions has had problems causing it to skip all over the place during play back (even on new discs). Maybe the problem is due to lack of use? Cost to diagnose will be $40-$150. So my questions...

1. Anyone familiar with it, or have tips on how to fix it?
2. Should I sell it and put the money toward another CDP?
3. Anyone know the value or want to buy it in this condition?
