My mom had one when we were all growing up, and we hung the clothes on a line in the basement. Soon as we were all married and out of the house, my mom got an 'automatic'.
Then, when I was first married we bought a used one. Had my turn with the wringers. I did like them, and they did seem to get clothes very clean. Just don't let the laundry pile up. Depending on how many of you there are to do laundry, try and do it at least a couple of times of week. It can be a long day's job, especially if you have to hang it all. It was nice to have a basement with a big laundry sink. Just run through the wringer after both wash and rinse, right into the sink. Drain the tub into sink. etc. Don't think I'd talk so nice about them if I'd had to set one up and use it in the yard, or on a cold porch though. They are a wonderful back up, prep item though.
