No, it is not a problem for you to email me. Thanks for being considerate. I have some information that will help in your research.
Below, is a link to a store called Dr. Clarks store.
My family and I order from here all the time. We have never had any problems getting our things. You can find the zappers here for the same prices as the ones that you were originally looking at; however, there is one other: It is called the Super Zapper Deluxe 2003, it is about $200. This is the one I have. I can't say if it is better than the cheaper ones, sorry. I made my first zapper. Yes, I made it my self with out help ( pat on back) Because of all the work that went in to making such a thing, I was attached to it. I had to send it to my sister because she was in such bad shape. I purchased my zapper deluxe soon after. I like the zapper deluxe because of all the interesting things that go with it. I plan on purchasing some cards this year. As far as the quality of the machine: it is plastic , light blue , looks nice and comes in a case.
Clarkia is a good choice. olive leaf extract is- also- good to take for parasites. I just started taking it; I'll let you know how that goes.
