Where to buy Audio Technica TT feet?

Hi, I'm looking for Audio Technica Turntable Feet, If you know where I can get a set/cost? Thanks, Rute.
I could be wrong but Audio Technica stop making those a while back and I think the company has gone out of business but I have a set of these I used them on a Technics SL 1600MK2 turntable helped reduce or eliminate feedback also are adjustable from what I can remember that was back in the 80s. EMAIL me Steve.Ardilla@mkg.com
Sorry made mistake on address Steven.Ardilla@mkg.com
As coouugar states they are no longer manufactured but they are from time to time offered for sale on eBay and suchlike, usually out of Germany so look in "international search". The set you want is AT605 Audio Isolator, box of four (if still in original box). Good luck, regards, Richard
Thank you, Rute.
Just how good are they?
