I got my lens. it is a sigma f2.8 ex dg macro. I have to be to work in a little more than an hour, and if I break it out, I won't work at all.
I'm also going to city knitting before work (and will try very hard not to spend too much time there) to buy undyed superwash sock yarn (hopefully) and then some gigantic yarn for a non-sock project.
it's, bad, though, when I say, "alright, me, stay below $80."
hooray for free government money!
