Dell Rollerball Mouse in Orange, CA

I have a plain and simple Dell brand rollerball mouse. No lasers, infrared or light beams shooting out like Star Trek to guide the cursor. Two button mouse, scroll wheel and basically plug and play. If there are any drivers I haven't found them. Mine is all black, but I used the photo below instead from the Net. This is cash sale only...PLEASE bring exact currency. Terry Orange near Hart Park
