I am building a new gaming rig and need to decide on a mouse. I play pretty much every kind of game, but mostly first person shooters where accuracy is key. I would consider any mouse besides a cordless or boomslang. I did a search and found the boomslang recommended, but I don't have enough $$$$ for one. What mouse do you all use for FPS gaming besides a boomslang or cordless??? Thanks in advance.
