That is an all in one solution. Its not really gonna get you good results at either I hate to say. I am sure there is an x-y table that would replace the tool post holder in the pic. One bad thing about it, is it doesnt look like the drill check is removable. If you try and mill with that, your results will be ......... not quite as accurate...... then with a tool holder or collet system. That machine was desigend for light duty, not the harsh work you sound like you are wanting to put it thrue.
Your best bet would be to check out
www.harborfreight.com or
www.jlindustrial.com or I think
www.wttool.com or do a search for whole sale tool.
Also another site to check out is
www.desktopcnc.com
yes most manual machines can be converted to CNC for about $1000 but this is for most small machines. Cost goes up when you get into bigger machines.
hope this helps
