cd transport life ecpectancy


Hi
I wonder what's the ecpected life of a cd mechanism .
I own a transport based on PHILIPS CDM-3 that according to the previous owner has few hours on it,and judging by it's general appearance of the unit(I just bought it) it seems to be in tip top shape.I plan to keep my unit. I was told 3000 hours life ecpectancy on the cdm-3 but I think of that to be rather low . There is a used cdm-3 on sale ,should I buy it for spare? or just leave it alone and if it breaks then I worry about it.I understand that cdm-3 is no longer in production and finding one is a difficult task.
Your ,opinions, please are welcome.
Best regards
George

I had a Sony ES89 5 disc changer, that was left on every day all day while I was at work (for my pets, and then also used by me when I got home, averaging 70 hours of use a week, for about ten years... 36,000 hours. and what killed it was only that the wiring from the rotating sled to the circuitboard developed a fault. THAT is a lot of time.
My personal experience is that Philips or Philips based units don't last as long as other units. 3000 hours seems very short to me for any CD player though. Sean

I've heard 10,000 hours minimum. I've had a Meridian transport for about 12 years with nary a problem.
