Back to the original post, I'd like to mention a website you've probably never heard of -- my own. :) I've had a large section of Ray Dream shaders for download since nearly forever, plus I do have several models available in RDS format. I've got Carrara but haven't had any chance to play with it yet, although I understand the RDS items still work in Carrara. You're welcome to drop by and have a look around. :)
