In all seriousness, get lots of good and varied advice before you invest in your own equipment. Also, if you have mates in the sport, ask them if you can try their markers (guns) before you buy. Then look to play the Masters KotH or similar to get started. Ask your friends to train you up or if that isn't an option attend training sites, ask questions, learn drills, ect and advance as quickly as possible.
Oh, and buy a PM7 and always shoot Draxxus paint through it!
