Questions on PHILIPS TRANSPORT MECHANISIM

Never heard of CDMPro2 breaking. This is one of the most robust mechanisms.

The one that was notorious for breaking is CDM-9Pro.

Of all the parts you mention only the pro 2 is easily available. It's good, one of the best Philips transports modules.

The CDM PRO2 is used in the large jukebox players you see in bars and everywhere else. I also never heard of them breaking. Choice of just about any player with a dedicated cd transport with a toploader which i like vs the drawer, less moving parts.The cdm-1 was an outstanding unit but do not make any longer. This unit is from the highend days of the late 80's and earyly 90's when transports where not made from plastic. This is one reason i looked for the CDM PRO2 for my transport.

The CDM-9 Pro is no longer available and was the finest transport for redbook ever made.
It was used in the famous Krell KPS 20i(one of the 5 best cd players ever made according to trade publications)
The CDM-9 PRO used the smallest error correction circuit of all of them.
The CDM-9 liked a clean disc and could track with incredible ease and let you hear what was there without substituting false info.
The unit was too expensive for Philips to continue to make so they came out with the plastic housed drives and caused an uproar with manufacturers which made many have to discontinue or completely redesign product.
I have a Krell KPS 20I and purchased an extra 9 PRO before they vanished and it is priceless to me, as to this day the unit is still the best sounding unit I have ever heard.
I would suggest much caution in buying any unit that uses a 9-PRO unless the seller could provide you with a back-up 9-PRO,because if it goes than you have nothing but a parts unit for someone like me and NO ONE and I mean NO ONE has any replacement 9 PRO drives anymore.
