Ah yes, I'd forgotten about that option.  There are several advantages to getting a mill and adding an extruder instead of a MakerBot:

- Since all axes are moved by threaded rods, not belts, it would have much better relative and absolute position accuracy.

- We could print much larger pieces than what MakerBot is capable of.  I have often found myself in situations where I wish I could print larger than 10cm x 10xm x 13cm.

- I have a spare extruder kit already, and there are designs out there for "printable extruders" that shouldn't be too hard for me to fab parts for.

- It has been done.  See Matthew's Flickr stream: http://www.flickr.com/photos/matthewlaberge/

Another CNC machine to consider is a Sherline CNC mill system:

Since we're in Canada, I'd suggest the metric P/N 8021A CNC Mill System with Accessory Package for US $2965.00.

Details of the Model 2000/2010 in that package are here: http://www.sherline.com/2000pg.htm
