Buying used is a good idea. They live a hard life in a cycling environment.
The best one to pull out of a pocket and shoot on the fly was a Panasonic TS25 (now discontinued).
Small, lightweight, simple to operate, water and shock proof.
I lost it on a rough trail ride in the woods when it bounced out of an unsecured pocket in my h'bar bag.
Sure do miss that little camera.
Looks like you can still find a new one on Amazon
