I went for the Ultra machine, which I think is still the most expensive machine (of the 'face-lift' ones), and I still draw a profit on it. The plain CACI is quite inexpensive, but I decided that having the ability to offer ultrasound, laser etc as well made it worthwhile as I have been able to offer 30 minute treatments for acne, scars, stretcmarks etc, the normal CACI, and a CACI combining the face-lift with the skin rejuvination technology of the Future-Tec. I have also just purchased the Hydratone for my CACI, and have already done a couple with more booked!
