Just to add,cost of the machine is one part of the equation, software is the other.

Ran a licence for Mach3 down to 115 GBP on ebay, without a licence your limited to 500 lines of code,which might slow things down or linux EMC for free.

CAM software, its possible to go for a while on trials but eventually you`ll want to setlle on something, personally went for Meshcam, chew another 175 USD, which from my own survey is good value for what it does.There is a lot of other choices but figure around 100 GBP starting point....

CAD sotware, used Sketchup for a while for other uses, but beginning to figure its not great for conversion to CAM models, probably time to learn something more suited and eat probably another 3 figure number there....
