The CL is a nice tamper, I got one a while ago and still use it from time to time. The rubber feels nice even though its less important in a domestic situation and the adjustment rings are a good idea. I do find the neck to be too skinny for my liking - compared to other tampers Ive used it feels a bit like holding a pencil so the feel in the hand is less positive. But then if youd only used a CL youd probably find other tampers felt too fat, so a lot does depend on what youre used to. The guys down at Veneziano use them among other things and have generally very positive things to say about them. When I use it I do miss the fitted base and the rings, but it still tamps my coffee a lot better than the standard Rancilio one does, theres no doubt about that! Also the CL (as far as I know) only comes in a convex base which may or may not be an issue for you. Youre probably the only person who can decide on the aesthetics as thats a very personal thing Ive found.
The CL is a well-respected tamper so if you decide to get one Im sure youll see a big improvement over what you have at the moment.
