Request Transport Help

I am currently using a older Rotel RCD-991 as transport into a PS Audio Digital Link III (with Cullen mod 3 upgrades) It sounds great but laser on Rotel is getting old (skips) so what is my best option here at lowest cost/quality ratio

1. I tried to hook up a Denon 2910 DVD player as transport and can't get anything out of the coax. worth fighting?

2. Put a new laser in the 991?

3. But a "cheap" new CD player and use digital out?

4. Buy a used transport only from my friends here at audiogon?

I'm wondering if #3, what cd unit uses the best cd-transport at lowest price?

Thanks for advice in Advance!!!!
