For a few months now, I've been wanting to get my hands on an old typewriter. Preferably, a manual (non-electric) one. And what happens to show up at the local Goodwill??
A mid-1960's Underwood Touch-Master 5. It's crusty, dirty, and needs a lot of cleaning, but it works! And it was a steal at $15.
My 11-year-old secretary couldn't resist playing with it. It's so tactile! And it makes a nice, solid "clack" noise every time you type a letter. What's not to love?
