Darn! I just sold my Mini about 3 weeks ago! Having said that, as much as I LOVED it all those years, after I had been using newer devices I went back to it and found it almost impossible to get along with - it was far more laggy, and even the small screen (which is why I loved it) was annoying me. I have switched to a Kindle as my main reader and find that the screen size is a really fair trade-off - it doesn't FEEL much larger and still fits in my purse (with a form-fitting case) but it is SO much faster and easier to read on.
I think the Clara is a similar size to the Kindle basic? Might be worth checking out a Clara or picking up a secondhand one. Good luck in your search!
