ZAPPER Info ~ HELP!

Immuno-compromised system needs help: Which ZAPPER?

Need to buy a zapper but by the time I get to reading more than one advertised product, everything begins to bleed together ~

This is a very serious situation and I prefer advice from experienced users, please. I know nothing about zappers outside reading on this site and unfortunately, my memory sucks and then it sux again, so I can't keep the info in the ole head, if you know what I mean.

Still, I trust this site and you guys and would greatly appreciate ALL feedback EXCEPT the bogus bs and sales pitches stuff.

OKAY! So what kind of Zapper do I buy? Although I'm limited with $$$ I'll spend $$ to get better. I'm fighting major stuff here so your feedback is very important and PLEASE don't get too complex or detailed.

I need something that will zap on as many frequencies as possible...I guess !?!? :)
Thank you ahead of time. :)
