One of the first transwomen I met told me about clearing her chest with this cheap home electro device, it's sold as the OneTouch now, or was back then? These things are really crude but some of us have gotten results with them, but you'd just as well find a used professional machine and carefully work on yourself.
I had to give up on electrolysis a few months ago; I was earning minimum wage and electro left me with no extra income whatsoever, after scrambling to pile up enough to pay property taxes. My operator was cheaper than most, too.
So, I bought a used Fischer epilator on eBay - Fischer is a respected brand. I've tested it and it works, but haven't done much with it, truthfully. I bought it with PayPal credit so it only costs me about $30/month.
This morning I found out I'm getting an almost $2/hr raise

so will order some more sizes of needles, magnifcation of some kind, Bono's book. I've taken a few stabs at removing hairs from my thigh to see if I have the knack, and it is a tricky business. My feeling is that, if you have the motivation and the patience, and, most importantly, go slow, you can do a lot of hair removal.
hairtell.com has a ton of info. One of the most prolific posters there is a Canadian transwoman.
The horror stories we sometimes hear a lot about bad electro are about people charging for their services, and doing a bad job of it. One local electrologist told me about her (trans) partner going to an operator who had a top-of-the-line machine, worked very fast, seemed to give very good results - but almost all the hair grew back. Other operators did bad work, too.
This person actually was so upset by her partner's ordeal that she went to school to become an accredited operator, and is now working full time in electrology - and 90% of her clients are transwomen. It was from her that I learned that Oregon actually mandates that electro be covered for the gender dysphoric. Oh, really? My previous operator was under the impression that only people earning Medicade level incomes had any hope of this sort. Since then I've heard 2 different takes on what insurance can deliver - an operator can charge insurance for their work if they're in the same facility as a surgeon? Some companies cover facial and genital, some just the latter?

Going to school would set me back about $10k, and my previous operator had a lot of expenses to cover, too. I don't really fancy making a career out of putting people into agonizing pain, either. Each state has its own regulations about this, too - or lack thereof. In Oregon operators must have their own workplace not in their home, and have accreditation from a college. In Washington neither of these apply.
Now I'm thinking I'll have laser on my face, and down the road see about electro for what remains, if I haven't developed the skill/confidence to work on myself. As is hinted above, there are parts of your face you can't really work on.
