I managed to score a sit-stand one with a hand crank off Craigslist. It's a little bit wobbly, which is annoying, but I'll live, especially since the price was superb.
Of course, it's turning up myriad other problems with this whole area. My monitor is too low now, and the bricks I've had it propped up on are ridiculous, so I'll have to do something about that. (This monitor has a VESA mount, and the gal I bought the desk from gave me a tip about a used office supply store...) And, like... either the desk legs are uneven or my floor isn't level (edit: it's the floor), so I'll have to do something about that too. (Where did my spirit level go? Didn't I own a spirit level?) And since the desk doesn't have a drawer, I should probably get some kind of system to organize the odds and ends that used to end up strewn around in there. I've got two boxes of nonsense clogging up my floor after cleaning off the old desk.
But I finally have a surface that feels good to type on! In my own house! And I can crank it down when I feel like pulling up a chair and playing video games.
In less positive news, I totally lost track of the mosquito I saw in here a few minutes ago.
