Finally a Rife Machine!

Finally I can get a Rife Machine but I have a couple questions since I am not really that knowledgeable yet about these machines. I am looking at an Atelier Robin F165 or maybe an EMX.

Which of these two would be best as a first machine?

I don't yet want to spend a lot of money and buy both at once. And, is it better to get a Plasma machine first, like the EMX? My understanding about Plasma Machines is that you only have to have them near you but not touch them as you would the F165. Is this true? (forgive my ignorance as I've only been used to using a Zapper)

I will mostly be treating Lyme.

Or if there is an even better first machine for around the same cost please let me know.

Any help or suggestions would be much appreciated!
