I've had two Sony 5-Disc CD Players & one 5-Disc DVD Player; however, they were not the higher end ES line. I never had a problem with any of the disc changing mechanisms; however, the very first one's laser failed after 10 years. The other CD & DVD are still running nicely after 10 years or more. I doubt that the newer ones will have such longevity.

The only problem that I see with what you are looking at is - How much life is left in them?
