Murkat

I need to, would like to invest into some decent detailing materials. I have notice that some of the sticky threads are a few years old. Any updates?
I am interested in a polishing tool, I notice the Porter Cable Random Orbital Polisher 7424 or 7336 model is mentioned. Reviews on it are sketchy, head piece separating from motor, etc. I am no stranger to Tools, big makita fan here. And I am handicapped in the hands, wrists. I fatigue quickly with pressure, repetitive motion, etc. Any suggestions? I guess I don't want to spend 1k on a detail when I can do it myself. (I repair, custom work, finish work musical instruments). J
