I would like to build a DIY cnc router for cutting wood and up to 1/6" Aluminum,does anyone have any suggestions as to what I would need for this project. Also the best place to aquire the necessary parts. There is a CNC router table on ebay that looks pretty nice style wise http://cgi.ebay.com/ws/eBayISAPI.dll...831826908&rd=1 price wise seems linda high to me for what you get. Thanks Greg
