Which is the "best" version of the stable platter mechanisms ?

or are they mostly the same ?

Without reservation, I can say the best is the system used in the PDR-09 cd recorder. It's the same beautiful mech as the PD-75/95/S95, but has a HUGELY better laser(which itself is vastly more reliable) that was actually designed to fit the linear motor sled, instead of the ridiculous adaptation of the standard changer laser into the linear sled done in the players. It's a really rare piece, though I did find one for myself & a spare, and just gorgeously built. A really close second, IMO, is the PD-S06, which has the lighter PD65/703 variety mech, but a very well implemented Kyocera tcxo clock. Such a great sounding player, though, it'd be a waste to use it just as transport. The Audio Alchemy DDS-Pro would be my third choice, being literally a PD-S703 with a reasonably nice added "superclock".

I'd strongly caution you about buying a PD-75/95/S95. The way that ancient PWY1004 lens-dropping laser is kludged into the linear motor sled can VERY easily fly apart in shipping(have seen it happen several times) & trash the laser or worse. In one PD75, client shipped it to me quite well packed, but UPS managed to drop it hard enough to make the sled fall apart, and little short metal guide rail used as part of that mount got under the main board & zapped to death the main system control processor, using the energy stored in the memory backup cap. Bizarre, and fatal to the unit.

So, a reasonably good condition PD-S703 would be a fair choice ?

A fair choice, yes, but no better as transport than a PD7700, PD31, etc.(assuming swapping optical for rca coax out, of course, which is very simple). The PD-S06 & AA DDS-Pro are quite substantially better, thanks to the better clocks. If you are considering a 703 due to budget, you would do MUCH better, and likely cheaper, to buy a PDR-04 recorder, which is same mech with near bulletproof reliable Sony burning laser. Again, you'd need to do a simple optical to rca coax output mod, for respectable performance, which would take about an hour or so to do on the model.
