I want to have a CNC mill to make PCBs on.

Requirements:
Working area: 160x100mm, 320x200mm would be nice but is not needed.
Precision: Precise enough for SMD.

Price:
Max 250 EUR + shipping.

I have access to professional CNC mills and lathes for metal work for the next couple of months, so I'm wondering if I should buy one or make one myself using a dremmel or similar.

I've been doing a bit of math and it looks like I'll be spending about 50% of my max. amount on motors and I'm guessing about 25% on a dremmel(not sure what they actually cost here in Denmark) and that leaves not a lot for the mechanical parts.

If I build myself I will use EMC2 from linuxcnc.org as a controller.

If I buy I'm fine with a good condition second-hand machine too.
