Logitech G9 for mac? yes? no? maybe so?

Basically, i run windows 7 and mac os x on my iMac - i do graphic design, photoshop and all that nonsense on mac os x so i need a good mouse for that...
I only use windows for gaming right now...

is this an okay mouse to use? any better suggestions?!?!
I'm willing to put in £40 for a mouse...
