I have my reasoning and 2 main factors lead me to decision you may not like. I'm going to go with steppers. Main reason is cost. Second main reason is that I want to start making parts quickly, and don't want to spend a lot of time on building CNC system itself. 2 main obstacles beside cost for DIY CNC are lack of knowledge of electronics and virtually no tools and skills for producing other required mechanical bits. After all, CNC supposed to be the way to produce parts for my projects, not another project by itself.
Beside this all there are other learning curves in front of me - CNC programming, CAM systems and CAD to CAM conversion. DIY CNC would add a lot of learning to already big pile I have in front of me. PS: Support from the group in my case was basically reassurance that steppers would do just fine for my needs.
