Re: CNC for PC boards?

They show a complete unit for $1395 at:

http://www.cnclinx.com/ebay_xyz/dremil_cnc.htm

my only concerns would be that the bearings on the slides look like
they are plastic and may wear quick.

I'd like to use a higher quility cutter than a dremmel (mabie a
linoleum cutter) from my understanding to cut PC boards the tool
speed should be about 10-20k

if nothing elese this would be a great start as it is of the type I
was looking for.
