KSS-240A based transport for DIY-Player

[Salar]

Hi to all,
I am planning to build some kind of "Frankenstein" DIY CD-Player:
The Dac will be taken from a Parasound D/AC-1500 with PCM-63K
The tray (I do not want a toploader) comes from good ol Sony CDP-103,
fully made of metal - this tray mechanism from about `84 weights about 3kg.
The case and front panel of this DIY Player will be milled out of alumium

But well, the pickup mechanism... I wanted to use a Philips VAM1202 mechanism,
because spares are easily available, but this mechanism is too flimsy and does not seem to last long.

I do now think about using a Sony based mechanism with the KSS-240A laser, because spares are cheap and easily available.

But looking at this list , I see theres is a lot of (used) players to choose from.

And here my question starts: Could anyone recommend a cheap player with digital out using the KSS-240A? As I said, I will use a good tray anyway,
so I am only intersted in the pickup mechanism and servo control.
Looks do not count, a digital output would be fine, the pcb´s should not use much space.
So did anyone collect experience wit various Sony Players using the KSS-240A?
Do transports using the KSS-240A differ very much?
Or did Sony use basically the same transports (same spindle-motors and feed motors for the laser, same control circuitry)
in wide variety of models, from boom-box to High-End-Heavy? (Like Phillips/Marantz did )

Too bad, the lasers of the CDP-103 are no longer available! I would have loved to
use the original CDP-103 Pickup mechanism, which runs on magnetic raiils...
All the best,
Sal

P.S: I made a version of the player/transport/DAC list for Filemaker Pro,
now it can be easily sorted, so If anyone is intersted, I could mail it
