You could try Jack Wooton who is an engineer has a large collection of CD players and seems to know his stuff.
He often sells on eBay and I bought a mint Phillips CD104 from him, he recaps them and deals with the gromet issues.
I ended up buying and sending a not so mint Philips CD303 to him for the same treatment. He did a great job. I spent ages talking to him on the phone and he was very helpful.
A couple of weeks later he was selling a mint CD303 from his collection for the same price I paid for my one plus the service and upgrades and I was a bit gutted as I prefer my hifi to be mint.
His user name is merlinboat on eBay. I can pm you his email address if interested.
