I've been using them for about a year and a half now, they're great! Only complaint is that it took me a while to add all the folders to Carrara's shaders browser, but that's not Clints fault. I hope Eovia will someday add the ability to add all subfolders in a group that would be great. In response to shaders should be free... many are, in fact I have several from Bremmer, Tony Lynch, Litst, the Danscape shaders, some from Digital Carvers and maybe LHS, some I picked up at egroups, and a lot that I copied from screenshots posted here. I have found all of them extremly useful working with my own shaders, sometimes it's difficult to decide how to go about creating a shader and I'll disect one that I already have to see how it's done. HEY CLINTH, is the screenshot you posted above of the RD version, I don't have one called "Frog Skin" is it the same as the Green Lizard shader, or is it one that didn't make the conversion?
