Help me choose a magnetic pulser!!!

My classic Beck pulser broke recently. I used it on a daily basis for a year and it really helps.
I am interested in your thoughts about which pulser would be best for me.
I have lyme and heavy metal poisoning. I am very detox sensitive. I already use a enem2 Rife machine once every couple of weeks (It took me years of agonizing herxheimers to get to my current high dose treatment), and I use the godzilla blood electrification daily now too for 3 minutes (all I can tolerate).
Three machines on the market look good: the M-Pulse 5000the Sota and the MPM2 Magnetic Pulser. I can't make sense of all the technical info. Help!!
