Hi CNCadmin,
l bought one of the complete kits from Tal at foamlinx.com. Spent a couple of evenings putting it together and works well straight out of the box.
Still learning the software and trying to increase the speed of the cuts but would recommend it, if you haven't time to put one together yourself.
Here's a couple of extra links
