If it skips easy on scratched cds laser may be going out. To many moving parts to pay that type of money for an old CD player.
I have an old Exempar Audio modded tube Denon 2900 that when it’s starts to not play scratched disc the laser is about to go out. I just buy a new laser off eBay for $30 and replace it myself. I don’t use it anymore but keep it for kicks it still sounds good for what it is, in its day it was $5000 now it’s worth maybe 2 to $300 to a brave willing buyer.
