I'm looking to make a motorized linear system to move a video camera (< 5kg), about 1m long. I'm a total newbie with this kind of thing but I thought a leadscrew and nut would be a good way of doing it.

For the intended use, I guess the accuracy/backlash etc is not really a problem so I'm just looking for something cheap but fairly reliable.

I was thinking of using SS leadscrew as it will be used in a domestic situations including outdoors. Is this 10mm leadscrew: http://www.worldofcnc.com/products.asp?recnumber=231 and this brass nut: http://www.worldofcnc.com/products.asp?recnumber=49 the right sort of thing to use?

Any ideas, cheaper suppliers or help would be appreciated.
