The Victor is heavier, the same for signal to noise ratio, and better for wow and flutter, so is probably worth slightly more than the Pioneer PL-707. They are both good turntables though, so it comes down to which is in better condition, and how easy they are to get without destroying anything. The Victor does have the advantage of electronic damping and antiskating for the horizontal direction of the tonearm, so cartridge resonance will be very low horizontally, which improves noise and distortion. See

The Pioneer PL-5 is significantly lighter, so worth quite a lot less. It looks like a cheaper model than the Victor or the Pioneer PL-707, but should be reasonable for the right price.
Ok, so taking into account all of this, we will cross out Denons (because I have a Denon device and because they are either with damaged cover or with no cover).
Also crossing out 445 - it has no advantages, the PL-5 is better (right?) and cheaper.
So.
Victor QL-Y44F for 500$ (from Japanese auction can be bought for 300$ including shipping - but I am afraid to pay so much for something so far away...) - 80 dB rumble, 0.008 RMS wow - what's the difference with WRMS?, Quartz, ? size platter, Qdamping
Pioneer PL-707 for 400$ - 80dB rumble, 0.025 WRMS wow, Quartz, 310 mm platter, VTA adj.
Pioneer PL-L800 for 312$ - 78dB rumble, 0.025 WRMS wow, Quartz, 320 mm platter, Linear
Pioneer PL-5 for 110$ - 78dB rumble, 0.025 WRMS wow, servo with speed adj, 310 mm platter
All of them are in perfect state.
The reason why I am not getting Victor right away is that I am highly in doubt, whether 2 dB better rumble, quartz and VTA are so important and worth 290$.
Or 10 more mm of platter, linear tracking and quartz worth 200$.
I mean if DC servo motor is in good state, the rotation will be same stable as with quartz, no?
310 mm should be enough for 12'' LP.
So actually there are following pros (comparing to the cheapest model):
Victor - Qdamping and 2 dB better rumble - 400$ more
707 - VTA adj. and 2 dB better rumble - 300$ more
L800 - Linear - 200$ more
If only any of these (even Victor for 500$) had 78 rpm option - I would take it right away!
But in this situation it seems for me that I will be definitely over-paying if not taking PL-5.
Maybe someone can point me towards some <600$ TTs with 78 rpm option and -58 dB weighted (-78 unweighted) rumble?
