Brent, I'm also having a difficult time finding out anything about this. Can you post a photo or photos showing the lettering on the converter? Thanks.

The lettering suggests this would be either a Tamron or Kenko TC.

I think it is Tamron. The going price, I think, is $80 - $120.

Is it any good? I don't know. I have one, but have never used it.

Note that it works with screw-drive AF lenses, but despite having the power contacts, does not with lenses with internal AF motor, at least with the ones I tried (Pentax DA* zoom lenses, Sigma 150-500mm HSM).
