I really can't afford fonts at the moment, I'm still a student; and prices for them are pretty outrageous anyway, but I really like Helvetica, which, of course, has to be a commercial typeface. Are there any other alternatives besides Arial / Coolvetica, which I already have, that I can use, that are very similar?

I'd ask for a download of Helvetica, but of course, there would be no help, and the usual 'you can't get commercial fonts for free / personal use' replies (though you can, it's not difficult for certain fonts, and very difficult for others; as a student who can't afford fonts, and music, really, I have copies, don't reprimand me, I love typography and editing, but I can't pay hundreds for a font family, okay? I know I am 'stealing' money from the hands of font developers, but if I can't afford it, how can I give them money for their fonts in the first place? ).


So, in conclusion, I'd like to know some good, free, alternatives to Helvetica BESIDES Arial & Coolvetica.
~Thanks!
