Hi All, Looking at getting a new mouse. The existing MS one isn't doing my railing any favours... I'm looking at either a Razer Diamondback or a Logitech MX510/518. I'd go for the 518 straight off except it doesn't have Windows 2000 drivers and I'm stuck with Win 2k for a while anyway.... Any used them? Opinions? Or others I should consider? Cian
