Vintage DD turntables. Are we living dangerously?

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.

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

Townshend Seismic Isolation Pods cost $675 (I paid about the same for my AT-616).
The Seismic Pods come in individual weight capacities of as little as 1-2 pounds per Pod, to as much as 64-140 pounds per Pod.

The set of 4 x AT-616 support 10 to 60 kg (22 to 132 lbs.).
See what’s inside the AT-616 , i like this design very much.

I never seen the AT616 anywhere in Europe or USA for the price you’re referring to (the price you mentioned is for cheaper and smaller AT-626). If you can find AT-616 for 250 pounds buy it immediately! I would buy two sets myself for this price if it’s true. 250 GBP for the set of AT-616 is a joke, it's steal, almost like a free gift! 

The AT-616 were about 400 euro even 7 years ago and now cost twice as much (or very near). I sold my spare set in 2019 and you can still read and check pictures if you you need more technical details here.

Anyway, the AT-616 is what i’m gonna use under my Victor TT-101 plinth @lohanimal

@chakster in fairness they are fairly intricate...

Out of interest do you use the JVC mat or another mat on the TT101? I have a SONY TTS 8000 but it does not have the OL2K mat and would love a modern alternative for that mat too
