I looked around for third-party drivers, and pretty much the best thing I found was SteerMouse, which isn't any more Mac-like than Logitech's, and is semi-poorly translated from Japanese, but is more flexible and doesn't require APE.

They were glitchy and not particularly user-friendly or Mac-like.

However, when I first installed the software that came with it, Logitech's drivers required Application Enhancer (APE, which I don't want), and they kind of sucked anyway.

I've had my Logitech MX Revolution for several years now, and I still like it a lot.
