I have been doing the same search! My Clipmasters just QUIT on me this past week. And honestly, I am tired of the weight and having the hair clippings blasted into my face. I had stopped using them because of that, but pulled them out because my Andis clippers have really slowed down this year.
I have a pair of Andis Power Groom clippers that have just slowly gone downhill - this year, they are catching in the hair, and just not working. So I just sent them in for service and a new blade drive. They were cleaned and serviced before, but no parts ever changed, so maybe this will do the trick. If so, I will be thrilled - have always used the T84 blades and could do a clip (all but legs which I never clip) in about an hour to 90 minutes. The last few high trace clips took over 2 hours w/ the Andis clippers, just sucks!
So I am following this thread too.
