Was that a CD63 SE KI? Those were legendary. You must be gutted.
IIRC the KIs were around £500 back in the mid 90s and were always something of a performance bargain. I reckon you'd be looking at spending around £1000 to get something of comparable performace to that unit.
The Cyrus CD8 SE represents something of a similar performance bargain and can be further improved by the addition of an external power supply.
CD mechs are a bit thin on the ground these days, though you might find a service centre with spares or refurb stock depending on type. Cost for the repair should be reasonable. Plenty of good players available at the moment, UK firms such as Naim (who I work for), Rega, Cyrus all producing good equipment. Or you could look at digitising your music and playback through a good quality DAC.
