Scopetronix 2" Barlow

These I believe are made by Guan Sheng and are being sold on e-bay and other places for $79...Joe O'Neil wrote that these are better than allot of Japanese barlows BUT wondered if anyone here has used one.

Jeffrey,
I have the same barlow which I bought for less at Owl Services for $59.00. It's an excellent barlow and cleans-up the edges on my TAL 24mm 2" eyepiece in my fast F4.5 16" dob. It comes with a 1.25" adapter and is threaded for filters. It's a shinning star in a world of dim barlows. PS If you do buy one from Owl Services, you need to call them and ask for it as it's not on their website.
