Are a lot of fun!
I'm now typing out a letter to my grandparents, and I'm writing this letter with a machine probably older than they are. I'm surprised at how good of condition this thing is, as I haven't really used it since I got it at a garage sale (20$) 3 years ago. The P key sticks, and it probably needs a clean, but it works well.
And there's just a majesty to hearing all the clicks of the thing, then the little bell as the carriage hits the end of the track.
What a marvelous machine...
