I would be the LAST person to talk anyone out of DIY. That said I wouldnt be in favour of a one-touch for you.
IlikeDIY's point is well taken. I would have to open up my defiled probe container and count, but I have destroyed well over 100 different probes while doing my face.Even with the increased cost of ballet probes for me, I WOULD HAVE GONE BROKE purchasing tips for the one touch.They average $5 to $10 each and are getting harder to find. With the number of them you will go through, you will spend well over the cost of a good used machine on tips for the one touch alone.
2) I found Galvanic VERY hard on my face. Remember these pictures?https://dl.dropboxusercontent.com/u/66437553/IMG380.jpghttps://dl.dropboxusercontent.com/u/66437553/IMG389.jpg
This is the result of the first time I had electrolysis with galvanic alone.For me the scabbing was horrible, and happened every time I tried my hand at galvanic. It's why I changed to blend so early on the scabbing was just way too much for me and I was afraid of scarring myself for life.
As for portability, a hinkel or clairblend is roughly the same size as half a box of chearios. I have 3 times had to take my Apilus ( arguably one of the larger blend machines out there) in a suitcase, with my optical loop, accross town to treat a transgirl who is disabled, by bus. Even with the larger size of my machine and the added accessories, I had no problems with portability.
The other huge factor with a one touch, is the amount of time it took to do galvanic. Combined with the scabbing issue, my decision to move to blend was easy. The amount of time to remove with galvanic was extremely tedius.The first time I had Nightfrost work with blend, one of my first comments to him was "You are going to LOVE the difference in time to treat a hair."
What I would suggest, if you are considering any DIY, is getting a used blend machine. Then have your pro concentrate on areas you cant reach, like under the jawline so the neck and under chin.As for cost, I posted a link yesterday in the ebay thread which included a sil-tone st250 for $400. That would make a fine first machine.
I had a very quick learning curve on insertions with reversed movements in a mirror.It did take me a while to get the hang of it, but it is the one thing about DIY I didnt find as hard as some made it out to be.
