Hi Phil,
Basically you're looking for something that's heavily over-engineered and, if possible, uses bespoke parts which are not used by every other 'Tom, Dick and Harry' CDP or transport.
Some of the models I would be looking at (note that certain ones will not come cheap) are:
Marantz CD7.
Marantz CD12.
Marantz CD94.
Sony CDP-507ESD.
Sony CDP-555ESD.
Sony CDP-605ESD.
Sony CDP-X707ES.
Sony CDP-X777ES.
Teac P1.
Teac P700.
Pioneer PD65.
There are also plenty more. Have a look through this site for examples:

Be careful though - only go for ones that you can still get parts for such as laser mechanisms, etc, otherwise all you'll end up with is a nice looking ornament if something irreplaceable fails!
In order to find out that information you would have to contact the manufacturer directly or speak to someone such as Mark Bartlett from Audiocom International on the forum who has worked on most of these units and has a good handle on which still have parts available.
Good luck!
For those who would like to see what the ultimate CDP looks like, and probably the best the world has ever seen, I give you the Sony R-10/DAS-R10:

F*cking gorgeous... *THAT* is what you call a 'statement' CDP!!
Marco.
