??Pro Optics Teleconverters??

Question for some of you accessory wikipedias. Who is/makes Pro Optics products and are they worth considering? Adorama and several others sell what looks like fully Pentax AF capable teleconverters

2XPX Pro-Optic Multi-Coated 2x Tele-Converter for Pentax Autofocus SLR Cameras.

A 2x with all the electrical contacts for Pentax Sells for $89.95

Let me know if you know anything. I have found some small sample shots and a couple of user reviews that looked promising. If you know something about these or where I can see a full review, I would reallly appreciate it.

I don't have any experience with it, but it appears to be a 4 element tc. The canon users indicated a lack of sharpness. the kenko mc7 2x tc has 7 elements in 5 groups and electrical contacts for about $50 more at Adorama. If I were to try a 2x auto tc, I'd go for the kenko
