I'm in the same boat you are, and so far, this is what I've found. Keep in mind some of the models are discontinued so a used one might be an option. CAL CL-10 or CL-5 (keep in mind CAL also made a multidisk transport only); any of the various Sony models including the latest SACD models;NAD; Nakamichi; Sonic Frontiers Anthem (tube output stage I believe); ADCOM GCD-700; Arcam made one for a short period called the MSX or MDX;Rotel; and if memory serves, Parasound made a belt driven changer.
Keep in mind depending on you finances, you may wish to purchase an older used changer to act as a transport and then purchase a DAC. This will be the route I will most likely take, as I have found it a good compromise between the convenience of a changer and the sound quality of a higher end component.
One last thing. I have heard all of the CD changers I listed above except for the Arcam. As stand alone changers they all have their strengths and weaknesses, but when you add an outboard DAC, the variables multiply. Therefore, I'm not going to recommend any specific component, but instead I would encourage you to listen to as many as you can find and make up your own mind.
