The response-time is much better with a wired mouse, myself have been using the Razer mouse series. They tend you cost around 80-90 euros but if you got the money and feel competative enough I can highly recommend one of their mouses. I've had quite many razer mouses but if you prefer comfort with less buttons (in comparison with the Razer Naga, for example) I can recommend you Razer DeathAdder.
