Before giving you any advice on what electronics to buy the guys in the know will want some extra details from you. Construction of machine for a start as to much power can rip the machine apart. Type of work you want to do with it, ie what are you hoping to cut.
While your waiting try reading this thread as it may help.

Thank you for your reply Martin. Much appreciated.
The machine is a moving gantry design made from MDF. The rails are 3/4 x 3/4 aluminium angle and the bearings are skate bearings. The design is from Buildyourcnc.com.
I will be cutting mostly 2-8mm acrylic, up to 15mm wood, and hopefully up to 5mm aluminium.
I was planning on using 8mm threaded rod for the lead screw, but your excel calculation sheet gives me bad results with that and 10mm and 12mm, possible because the pitch is so fine (1.25).

The lead screw will be 1300mm long on the x-axis.

Edit. Ok 8mm works fine now. Here are my results.
