I used to tweeze out my entire beard. At first the pain seemed unbearable, but you know what--after a while I got so used to it that it didn't even bother me any more. In fact, the real pain problem was cramping in my hand as it made thousands of tiny repetitive movements. I got in the habit of always holding tweezers and constantly plucking all day until cleared.
It all came back, of course. All of it. Ultimately, tweezing made no difference in hair growth. So if you plan on electrolysis, just leave off plucking for a few months and you're good to go.
A few months ago, I stopped tweezing because of concern I was damaging my skin with it. I started to notice dark marks which were apparently subcutaneous blood. I stopped tweezing and the dark spots cleared up, but I decided it's safer not to go that route. As for waxing, I don't know - I have sugared my whole body with good results, but it had no effect on my beard at all.
It sucks, but ultimately there's no alternative but to shell out the big bucks and get electrolysis or laser. With today's laser technology, it looks like a superior alternative to electro -- if one can afford it.
