Dear Jer,
The ones on this page are ones I like:
http://www.puttingzone.com/putters.html.
There are others, as well, but generally, no, I haven't tried to rank or rate putters. I will be doing that in the near future, though, and will have a complete testing, reporting, and "consumers union" / "JD Powers" type system of evaluation for value and performance.
I'll probably have to have a panel or community of volunteers willing to try putters out according to a regime or protocol that standardizes the evaluation from a consumer perspective, so if you are or anyone else is interested in helping with that, please send me an email and I'll start collecting names.
Cheers!
