Dave Don't buy anything yet because you'll be making the classic mistake often made by new people and will blow money big time.!!

The fact you have looked at this kit tells us that you haven't done any home work really because if you had you'd know these are complete pile of Crap and absolutley no use for the machine your thinking to build.

Irvings Advise is sound advise but from the looks of it you really need to go away and study the forum and build logs because to build a large format Cnc machine requires you have a sound understanding of how to go about it in every department.
The electronics are KEY to a good machine and for a machine thats running R&P even more important you get it correct because it's very inefficient compared to ballscrew machines so Motor and drive selection is critical.

Honestly your approach of buying each month is not a good one at all. You'll be much better off putting the money in the bank and swatting up on whats needed then start with the frame and work up from there buying electrics and stuff just before required.
This way you'll be much more informed of what's actually needed and you'll save a load of money on wrong components.
