If they are charging $4.00 for a site that has no activity then that is fraud and they need to be shut down.
On the Tascam people question, there are a few of us out there. As to their being an Engineer from Tascam is he from Japan? I was a Lead Tech in Chicago (Factory Service) and I openly help people to my ability even world wide. This site is great with it's focus on Tascam as we can see but there are other sites one can gain help at and one of them is Tapeheads.net. They have over 18,000 person there that are involved with tape. If you have analog Teac or Tascam questions I will offer my assistance where I can- of course I do not sit here all day long as I am working a shop pretty much by myself- I have to work a 42OB and a 58 next.
