These are all the sorts of comments I was after. Many thanks to all who have contributed. Cutting 3mm ali front panels is the primary use, so...

I had wanted to buy British... but now find myself looking at the Heiz models again. Certainly the videos and pictures on the website show very clear examples of my intended uses, and the pcb work looks to be an order of magnitude better (although I presume this could be down to the skills of the coder as much as the abilities of the machine?).

Particularly impressed by the deep ali milling on the first video of http://www.cnc-step.de/en/applicatio...und-weich.html

Thanks again everyone.
