I understand very well your point of view, #34548.
But buying without understanding what you are buying and what could be its use could lead to disillusion. Can you afford this?
Could you have help from a familiar able to make a reasonable choice in your best interest?
You can buy a Beck Pulser with this company, having most of Bob Beck’s devices, built under Becks recommendations. Not cheap, but quality is there. Company’s name is Sota Instruments : sota.com
They have too a Pulser/ Colloidal Silver maker (bob beck’s zapper), on the best Beck`s tradition
If you want to stay with Beck’s protocol, scadaresearch is another trademark to check.
Hulda Clark ’s zappers are more popular, so you can have more choice.
Avoid zappers plugged in the 110/220v line. They are unnecessarily expensive.
Don`t trust publicity is it looks too beautiful to be true.
Try to have a 2 frequency zapper as a minimum.
You can have a “great zapper” for less than $100 (and more too)
EBay has many under this price. Parazapper and Maestro-Zapper are two good brands I know, to check. There is others too.
The main point here is to buy a well built one (try to have a look or picture on the inside of your future zapper) and start zapping with care ASAP.
And please, don’t put your IQ or brain fog in front of your quest.
Ask direct questions until you have “good sense” answers.
