For those curious, I dug up some crappy (but mostly understandable) English subs for episodes 21-35 here:

I'd say success, but the sub links for episodes 2-20 are not working anymore and episodes 36 onward were never completed at all. Looks sort of like an English translation put through a machine and maybe edited a tiny bit by someone who doesn't speak English as a first language. I stress again though that they appear to be mostly legible, so...huzzah? Hoping I can find a mirror or something for the rest because this is thus far the only (more or less) full translation that exists as far as I can tell. Enjoy.
