Ask HN: Good small mouse?

I want it to be: - small - wireless - tics in the scroll wheel - easy to press wheel - 1600dpi or more - not too expensive

I like the no-names for 10 bucks, but especially the wheel/middle buttons keep failing. (like http://www.amazon.com/Perixx-PERIMICE-710R-Wireless-Mouse-Laptop/dp/B006UIFTTS ) I bought a logitech M325, but the resolution is to low for my preferred mouse speed and I keep scrolling by accident or while pressing the middle button, because there are no tics.
