When I say gaming I mean 5-button. I like those forward-backward buttons and I rely on them heavily. I'd prefer something ergonomic, but if my budget is too low then what the heck. I've had a £10 TeckNet mouse for the past 2 years and it's been okay, just not the greatest position for my fingers, which hurt after prolonged use. I am, of course, right-handed. Right now my best bet is to get the MSI Interceptor DS100.
