If you are in Southern California, Samys Camera carries them for same price as Jag's website. As for thoughts on it, its plastic...there I said it. Its for those looking for a cheaper solution but unsure of quality with the straight from China stuff. I own the v3, the a/b stop china focus, microfocus blue and the genus focus. Genus is by and far my favorite but the dfocus does not have any free play or backlash which I cant say for the stuff from china or even the redrock blue.
