I am one in the same person, although I went on to learn professional electrolysis from some of the great advice from some of the other pro's here.I did all of my own facial work, here as a DIY'er.
what machine you choose may depend a lot on what part of the world you are in.I would look at a machine capable of blend. I've gotten a lot of mileage out of my apilus kit but there are lots of great machines made by sterex, fischer schientific, silouette tone, instantron, claireblend, to name a few. I feel the low intensity rf used in blend makes it safer for DIY than thermolysis alone. Blend works extremely well and it is the modality I learned first. I still go back to it often.
