Hi, I am looking into purchasing a caci ultra second hand machine. Can anyone tell me what the hours are about on the machines please?!!! Do they have a set amount of hours that they will work before service, or do you then need a pin code etc? I have read nearly every post possible on this site to do with starting up a business (as I am hoping to do) but any advice on what to do or what not to do would be greatly recieved!! I am an experienced therapist and lecturer but actually going alone is a completely scary concept for me but something that I always wanted to do! Thank you geeks x x
