The real question is wear vs price. Hard to judge from where we are standing. The grime & handles that's easy peasy. Renzetti says the slide bar & feed mechanism is the heart of the machine which I believe, kind of like the lathe bed & dial feeds. If the price was real good & it didn't have a lifetime of hours on might be worth it.
I actually don't know yet what constitutes a proper collet set, it surely must vary by person. Some shops I imagine spend say 80% of time on a few common shaft sizes resharpening. Or maybe even grinding tools in production mode so they do 100 cutters all with 3/8 shank, that type of thing. There are also other fixtures to mount irregular shanks that so that's another option. I'm looking forward to getting service out of mine, especially custom cutters.
