Linn LP12 turntable

When you buy a LP12, you need to remember that you are essentially buying a modular and upgradeable system. The fact that the table was originally built in 2000, or even earlier, would not concern me. The main upgrade path for LP12’s is as follows…1) bearing, 2) subchassis, 3) and this can be swapped with 2 in my opinion, is the power supply, 4) tonearm and lastly 5) cartridge. Albeit, I have recently acquired a new corner braced plinth, which was a nice upgrade…and might slot in between 3 and 4. 
If you are hampered by a non-concrete floor that has any way of flexing, then I would suggest a wall mount platform, or if that is not possible, a very lightweight stand. The Trampoline 2 baseboard helps greatly in this manner, but it is not perfect if you have floor issues…or standing wave issues. 
As to set up…don’t do it yourself. Period. I know there are folk who were prior auto mechanics and the like who will disagree, but a great set up by a Linn LP12 specialist is well worth it. The old thinking that the table floats out of set up once dialed in correctly, is simply not true anymore.

Lastly , I would suggest getting exact particulars as to the specifics of the table you are considering. So far, it seems to be a good deal, but it should still have a good set up done on it regardless. 

…and to get the most out of a Rega…you should also wall mount it….

Thanks, in either case, wall mounting is not possible, every inch of space is spoken for.
As far as foot faults are concerned, I don’t believe that will be an issue. The system is on the opposite wall from the entry door & it has only been an issue changing the record, stepping heavily when right next to the turntable. 
Assuming the right options are installed, and they support a trial, I will know quickly if that is a problem. 

I believe that the LP12 is actually relatively immune to foot falls, particularly if one is using a Trampoline 2. If there are issues, a very lightweight stand, like a Sound Organization, or a Target stand..and if available, a cheap IKEA Lack,will more than likely solve the problem. 
The only issue with an older LP12 with a Valhalla power supply, is that this is not compatible with the new Karousel bearing, which I believe is the best bang for the money in upgrades…and would be the first thing to change out, even over the prior Cirkus bearing. Nonetheless, a Cirkus LP12 with any of the arms mentioned would be a fair price at what you can acquire it for.
