motor advise needed

first let me say , i am not cheap , however i am on a tight budget
since i live on retirement income from uncle sam .
that being said i need to buy some motors to convert my van norman
no 12 mill to cnc and i cant really afford new ones at this time , i
will however get gecko 340's and mach2 to run it all. maybe new
motors late next year as the used ones fail.

so which of these used motors would be a good choice
