I have never been a huge fan of wireless mice but this could change...................

MX Revolution is my favorite Logitech mouse, mines running on to 4-5 years old with many hours on it. unfortunately its not in production anymore, I do see it online by 3rd party suppliers but the price is almost dubbled from what I paid. This might be a nice replacement
But I don't see a left hand option. I believe about 10% of the population is left handed, so I guess that's why, but it seems it wouldn't be that difficult to design the shell for a left hand and still use the same buttons, leds, and circuit (with some wiring changes.)
Saw this quote somewhere on the Internet: "If the right side of the brain controls the left side of the body and the left side of the brain controls the right side of the body, left-handed people are the only ones in their right mind!" ;D
yossam, my favorite mouse of all time (and I've been using the same one since they first came out!) is my Microsoft Wireless Intelimouse Explorer 2 http://www.amazon.co.uk/Microsoft-Wireless-Intellimouse-Explorer-Metallic/dp/B0000AKML0 (http://www.amazon.co.uk/Microsoft-Wireless-Intellimouse-Explorer-Metallic/dp/B0000AKML0) Heavy, built like a brick outhouse and quite accurate, although sadly I don't think they make them any more. You can say what you like about Microsoft software, but they make damn fine hardware :-) I have used (for a brief time) one of these http://www.cyborggaming.com/prod/rat9.htm (http://www.cyborggaming.com/prod/rat9.htm) They are absolutely amazing, though not quite heavy enough for my liking (I do know someone who has weighted theirs) :-)

I had a RAT 7 for about 6 months...................the pads on the bottom wore down so thin it wouldn't work anymore. :o Was even using one of their pads.
I have been using a Logitech wireless optical mouse ever since I built my Dragon computer. The optical means I never have to clean the wheels (that aren't there) and wireless means that the wires in the cable (that isn't there) won't get metal fatique and eventually break. I have two NiMH batteries in the mouse so I can recharge them hundreds of times. I almost don't have to service a mouse any more except that I do turn it off to make the charge last longer when I'm not using it. I am a convert.
