Just had a new CPC catalogue arrive on a colleagues desk here in the UK, and while browsing through it, in the PCB consumables section is a "Low Cost CNC Kit" for GBP256.02, catalogue #PC00380. It does require a Minicraft Drill model MB150 (CPC # TL-MB150) Don't know if this is also available in the USA, but it sure would come inside the US$500. Might be too light weight for what is envisaged, but for the price is probably about as good as you can get. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
