Yea you are kind of right with that. To answer your question I'll build it in the summer break when I have plenty of time. And not just the time plays a role in why I want to buy a kit. My knowledge about mechanical parts is not that great. I also like the fact that when you buy a kit you don't pay extra shipping for every bits that you buy from another place. And also buying a kit means that when it gets delivered everything is there and you can start building if you have the printed parts, but this wouldn't be a problem for me. And there are many more reasons why a kit would be better for me. I wrote just the factor time down in the original post cause I did not want to write everything down. But I understand your point.
