Tracking down a book for class got me into a whole mess once. My professor assigned this obscure translation of an ancient play, and it was out of print everywhere. I ended up emailing a retired professor in another state who had a copy, and he mailed it to me for free. The whole hunt took weeks, but it made me realize how much stuff just falls through the cracks. It's cool that you found your book at a shop that makes a point to keep those titles around. Makes the search part of the story, you know?

That adjustable sensitivity sounds like a game changer. Did you have to play with the settings much to find the sweet spot, or was it pretty straightforward?

But you're paying for the whole machine.
