Amazon offers the Corsair Vengeance M65 Laser FPS Gaming Mouse in Black, model no. CH-9000022-NA, for $39.99 with free shipping. That's the lowest total price we could find by $16, although we saw it for $5 less after rebate around this time last year. This USB mouse features an 8,200 dpi laser sensor, dedicated programmable sniper button, aluminum unibody, and selectable response time.
