3000 to 5000? How did you fabricate that? the most expensive device is the F170 at $1499. The F125 is only $516.
And F165 is as much as anyone needs at $1016. They all go to all the frequencies. Not just some of the frequencies.
"For the price of less than $350, there is nothing out there that matches a ParaZapper MY. Period."
Not true. A Beck approved Sota Silver Pulser is only $250. And It also makes EIS Silver solution.
I think most of the CAFL frequencies and the Crane frequencies are questionable BS. If you don't have the exact equipment Rife was using you're wasting your time.
