I'm interested in getting a Beck blood purifier, Colloidal Silver maker, and magnetic pulser, but see reference to so many different product brands. I would like to stay as true to Beck's protocol as possible and would like to wear the blood purifier around arm and wrist for long periods and still be mobile.

I have a clark zapper but don't like holding the coils, plus I feel that near the wrist veins is more effective.

Also I've looked at a few websites and the prices that are being asked are soooo high, when Dr. Beck was referencing $30-$40 costs per device in his video. What's up with that?

Also has anyone built their own devices using Beck's blue-prints? Are these blue-prints available anywhere, especially the magnetic pulser ?
