I have the newer G15 and G9 mouse and I think they are both fantastic. I love the ability to program the G keys on the G15 plus I love the ability to set custom game profiles for my G9 mouse.
Recently I also brought one of those gaming pads to try out for my games. I brought the Thermaltake Flareboard and I must say that I am very impressed by it and now I tend to use this over my G15 when playing COD4 and COD5.
