Interesting attempt to capture the low end of the market. As a Replicator owner (and a "Cupcake" user) the things that make for a good 3D extrusion printer are rigidity, flow control on the extruder, a heated build platform, and most importantly <i>moderated air flow</i>. All of the 'open air' printers suffer from print failures when a cool breeze causes the plastic to freeze to quickly, shrink and then warp off the platform.<p>Bottom line is that you can build your own Reprap for less than $500, get to know it very well, and have a lot of fun. But if you want to buy a 'tool' and start doing 3D prints with it, you probably won't be satisfied with the < $1000 printers out there.
