I've gotten somewhat annoyed with everything getting sucked into the death star that is Facebook. What happened to the
open searchable internet envisioned in the 90s?
That being said that particular group does have some good information on which frequencies work best.
In a nutshell:
The Doug Coil is basically a PEMF device that uses a coil to generate strong magnetic fields. Particular Lyme killing frequencies can be selected using a hardware control panel with switches. The fields penetrate the body extremely well including tissues like bone.
The downside is that the coils overheat quickly and so can only be used for 20 minutes or so. Also you are limited to relatively low frequencies and cannot sweep so if the bacteria mutates a bit it might be able to escape the fixed frequency. Cost is around $1500.
Rife devices have a frequency generator that is generally more flexible than a Doug Coil and depending on the device can output frequencies up into the Mhz range.
Cost can range from $200 for a Spooky2

Generally contact devices that use handheld electrodes to transmit the frequencies are the cheapest while devices with plasma tubes are more expensive. Plasma tubes act as an antenna which creates a field that penetrates into the body in a way similar to the Doug Coil.
As far as track records go the Doug Coil and the GB4000 probably have the most number of "cured" individuals.
Sometimes with Rife it's required to continue using the device once a month after symptoms disappear to prevent relapsing. Since at this point the treatment cost is essentially zero I consider this acceptable.
Personally I think the Spooky2 offers the best value for the money at the current time, but it's a newer device so less of a track record. It's quite inexpensive (~$200) for the basic contact mode frequency generator which is controlled by free software. If you want to increase the power there is a plasma tube amplifier which can be added to the generator for $1700. The power of Spooky comes from the fact that it's partially software based and so is constantly being updated and improved based on what the community discovers.
This is a great forum for all things Rife.
