I own several pices from proxxon. Later I got some tools from Facom and Beta. I'd wish I bought more of them instead of Proxxon. Proxxon isn't bad. I just prefer the surface and the handling of the Beta and Facom tools.
It is difficult for me to explain that. I am one of those people that "celebrate" wrenching. I don't just try to bang something on, without regard to losses. I initiate the repair by preparing all the parts and equipment, do the job by the book, keep everything in order, clean everything up later and get upset when there is a scratch on a tool.
