Bpoletti, I would never again run an air bearing arm on a suspended table. If I had to use a TNT, I would get rid of the 4-corner suspension and install some different footers in their place. There are a lot of good candidates on the used market.
The arm would be around $1200 - 1350,including insured UK mail
depending on options. For about fifty bucks more you can get a digital VTA scale. There seems to be a cult of tweakers gathering around this arm and its fans really seem rocked in their enthusiasm for it. I have too many other irons in the fire right now after huge system relocation, new speakers, tubes, cables, rack. I am waiting for a new UberBuss and will soon start screwing around with room tuning and speaker placement. A new tonearm install on top of all that will drive me nuts.
It's a back-burner project for me until I get a handle on all the changes I made already. Maybe next year. But I will probably obsess over it until then. It looks like the manufacturer has been responsive to his customers for years and is continuously evolving the design using their input. They seem to try very hard to make updated technology available as cheaply as possible for their existing customers instead of herding them to buy new models.
