Someone get into Mom and Dads liquor cabinet again? This price has to be a joke. When I bought it years ago, it was maybe $29.

Shit’s gone up 
I’m eyeing my old marble mouse (bought at a reasonable price) and really, really hoping it doesn’t ever crap out.
There are some non-Logitech trackballs out there which look like they ought to be at least be similar ergonomically.
Have they stopped making them? Is that why they’re so expensive now?
I got the top of the line MX Master 3S for less than this.
Yup. Logitech seems to have given up on ambidextrous trackballs. Turns out there’s a very dedicated - but apparently very small - market for them.
