Zapper Confusion!!

I've been reading so much about the different kinds of zappers out there. I need to get one to add to my parasite cleansing routine and don't know what to get. I've been cleansing for the last 2 and a half weeks with Dr.Clark's regimine with good results. I also completed a Liver Flush (my 1st)a week ago.
I know I have a long way to go and would like to do the right thing. Cost is always a factor so i'd like to find an inexpensive zapper that will get results.

What is everyone using?
any recommendations?

Thanks for any advice! Tweet
