[KwartzLab] Noisebridge & Techshop team up on a 3D printer

[Chris Bruner]

Since we are comparing, this is one that I've had my eye on for a while. 
http://printrbot.com/shop/plus/
8x8x8 build volume, laser cut birch construction,
no info on speeds
This was originally a kickstarter project.

Or a new one coming out, that is designed to be for normal everyday home 
use. http://makibox.com/
I'm thinking this one might be good because it isn't supposed to be fiddly.
