Vintage DD turntables. Are we living dangerously?

I will say this. The TT101 and the other Japanese Uber decks may well be a pain to service now - they are complicated - they were back then - they are so now. 
My only question is - is it really worth the bother?

I have the same stock plinth from QL-10 but the color is much darker. I like this small plinth better than the one designed for 2 tonearms. Stock feet is garbage, the best are AT-616 pneumatic and this is what i’m gonna use. Will put my Technics EPA-100 mkII or Ikeda IT-345 in this plinth.

If a buyer can repair TT-101 in his own country then it is worth the investment for sure! But at the same time some killer DD turntables like Denon DP-80 are cheaper and almost always in perfectly working condition (same with my beloved Lux PD-444).

P.S. Victor UA-7045 is a very nice tonearm if the rubber grommet is strong enough to support counterweight (or must be replaced with a new one). After owing various samples of NOS or perfect 7045 (and some not perfect ones too) i finally upgraded to the UA-7082 and now with Victor MCL10 cartridge it is a killer tonearm! 

Dear @chakster I've seen you mention the AT 616 legs before.

My problem with them is that the cheapest set i have seen is about £250.00. I do not have a problem affording that but there are modern options by Townshend that are worth exploring. Likewise I just find the thought of accessories costing as much as many a component a bit silly.
That said I would like to know what goes into their design

there are effective and much cheaper solutions, for example the Gaia III of Isoacoustics (36 kg set of 4) that work very well and cost significantly less even in replacement of the original feets.

Feet are like religion; everyone has his favorite.  I'm not a particular fan of the AT616, but is 250GBP similar to the cost of a component for any of us crazies?  I would have thought not.
