How manual are you talking? If you go for an electric typewriter with a Daisy-wheel, it can handle the spell check and corrections without you needing to pull out the white out. It also doesn't tangle ribbons like older models.
The older you go, the heavier and fussier the machine is going to be. I have to use a Lois-Lane approved, stilt-keyed chunk of semi-movable iron for doing school work when I was in high school. (This was my great-grandmother's machine, and it was after the rise of the personal computational contraptions. The typewriter was free, and a computer was not.) Using that monster, while it got the job done, was not fun. Typing quickly is difficult, thanks to the pitch of the keys, and the fact that the strike plates would lock.
Getting an electric Brother was awesome compared to the old-girl. (I'm wanting to say it's a Smith-Corona, but I'm not by any means sure.)
If I were you, I'd check local pawn shops or repair shops. Even ask at Staples, Office Depot, etc to see if they've got any in the back room that they want to unload. Our local store carried then - in stock - until about four or five months ago.
