Got a Razer Deathadder, they come with their own OSX drivers that seem to circumvent the issue. Also sad to see so many Magic Mouse users here ;) I know everybody has their own preferences, but that is not a good mouse.
I actually used a Razer Imperator, but I found it to be very flaky: about once an hour it would lose the plot completely and I'd have to unplug and reinsert the USB cable. Not a great experience in-game :-( I don't know if it was that particular mouse or the OS/X driver that was causing me problems, though.
I switched to a Steelseries Xai, and I've been loving it. It doesn't have any special mac drivers but all of the fancy settings are controllable via a little LCD screen on the bottom of the mouse.
I'm not sure if its affected by this "32 ms" problem. I only use OS/X so I might just be used to it at this point.
I have a Deathadder 3g Spawn and I don't use the Razer drivers.
If I look at my mouse in the app "USB Prober" I see OS X uses a 2ms interrupt to poll the mouse. If I'm not completely off that's 500Hz. More than the 125Hz that seems to be default USB polling frequency.
