well I guess that would depend on how much you want to spend in either time or money....
The ball screws/nuts that shoptask sells is from Nook industries, they are rolled screws precision about 0.004/ft. What you pay for from shoptask is there is a guy that "adapts", the screws to "plug and play" into your machine.
that is what you are paying the 800 for.
IF you can turn, and center drill acuratly the screws yourself you can save your self alot of money buy doing it your self. but remember the screws are HARD!!!
Nook also sells much higher accuracy screws....BUT, given the fact that unless you are able to PROFFESIONALLY scrap your ways, saddle, and get ALL the flex out of the mill quil arm on the shoptask, it would be doughtfull that you would get higher accuracy than the 0.004/foot anyway.
If you have the money, get the screws john sells for the machine, advantage is, if you get them and they are screwed up, you can return them for a replacement. IF you do your own screws and mess up, you buy a new screw and try again... If you have the talent and experience do it yourself, if not, buy Johns screws...
