A decent little (PCB miilling) Chinese machine...

[HankMcSpank]

It's hard to think of a way to make a CNC router what wouldn't do a good job of making that PCB. I guess if it was made from MDF...
Also notice how some of the holes aren't even in the center of the pads!

The grey machine is made from PVC...

Re the grey machine, yeah, PVC...I know, I know...but I guess it boils down to what you're cutting (the zentoolworks CNC is made from a similar material and folks seem happy with it)...not everyone wants to mill girders! (as an aside, I always think of the IRN Bru advert whenever I hear the word girder Irn Bru Advert: Shipyard Boy - YouTube "Made in Scotland from Gurrrrr-daaaas" !)

Re the smaller machine, I was just struck at how well put together it looked (especially the control box!)...compared to the usual Chinese fayre.

Anyway...shouldn't you be milling a girder? ;-)
