its cheaper to buy one than build one. not to mention firmware maturity should be seriously consider

put in layman term, the open source software share by builder are like 'Linux' OS. its basic, fully customizable(know/how knowledge very important) and functional. it might not be the best out there but it get the job done.
that being said, the 3D-printer manufacturer usually include their own developed OS, much like Window OS. it's fancy, friendly user and functional but less laggy (correct me if im wrong).

guys, my point here is not to undermine your interest nor this community. im technical guy myself and i like this kind of stuff. If in future i have time and money to spare i would definitely into this hobby.

cheers to you all.
