Logitech make a great mouse here Its what i am using now and you can get it on sale for <$20 I got mine for $23 a few months back. I also have 2 MS opticals. but the one (Explorer 3.0 USB) was a little more. Dont know how much it goes for now. I am loving the Logitech though, I would recommend it to anyone. Good for right or lefty's too.
The majority of people I know go with Microsoft and Logitech mice, but me, I like A4Tech. They may be a lesser known brand, but their mice are pretty good quality and cheap too. I use their wireless optical mouse and it set me back about $30USD.
I used to swear by my MS Intelieye Explorer. I swore they would have to pry it from my cold dead hand to get it from me. Then I tried a Logitech MX500. Now the Explorer does closet duty and they will have to pry my MX500 from my cold dead hand if they want to take it from me
EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
