Another happy TW user, in my case the Raven one. I have only had one problem, static build up in the Controller, which suddenly caused the platter to revolve at 300RPM/minute plus. I understand other users have had a similar problem, but it has been sorted now. The table was already 3+ years old, but I was given an updated controller with no quible. You can't argue with that for customer service.
If you want to economise on the arm and the TW arm seems uber costly to me, Thomas recommends the Ortofon arms and I am very happy with the 309D arm, currently with an ortofon SPU
