[John S]

would these be ok running from a cheap 24v 10a power supplies?

and could I hook it up to something like this http://www.diycnc.co.uk/html/pcpps.html

and have quite a cheap setup?

Yes,
Providing you are not trying for a low earth orbit then yes they will work satisfactory and give you what you are asking for, a cheap setup.
