I built a CNC 1.7m x 1.3m with 800+ IPS for ~2000$ - with a lot of googling and persistence. Ping me if you want to build your own, I'll give you details, it's really not that hard at all.
No, nothing online. It's a standard gantry 3-axis mill though. Pretty much all info to build your own is here: http://buildyourcnc.com/ I wish I found that info before!
