A little bit of help; Always works!!!

Hi all,
I am still undecided what to do whether to buy a ready made CNC like the Taig milling machine or to retro fit one myself. Personally I would rather build one myself, get a small milling machine and you know do it myself. But I am worried about the electronics of it and the software sides of thing!! How have people done this?? Is there any literature that anyone knows of like a step by step guide to converting a machine?? Any companies that supply the electric gubins??? And the software?? I start getting lost in it all?? Should I just buy on of these small CNC machines??


Thanks for Reading!!
Anthony
