The Griz probably won't satisfy anyone working on razors - only one size contact wheel, and no variable speed, even with pulleys. All I know about the coote is in the above post. I'd want to know how it worked for a razor maker before I bought one. I have a KMG with a variable speed set up and have never regretted the money spent. I strongly feel this is a case where you get the very best you can possibly afford --- the first time.
