Being in the US, try pbgear.com, paintballgateway.com and google for good places to buy paintball gear. Until you've played a couple more games and familiarized yourself with paintball a little bit more, you might be better off holding off on a marker for now. If you only want to play in the woods, or in scenerio/rec games, you might want a nice cammo'd out Tippmann A5 with a 18" barrel to sneak around the woods in. If you want to play tournament ball, or modern air ball (paintball a smaller field filled with inflatable obstacles, or "bunkers"), you might want an Ion, or a nice used angel or something like that. Try your local field, ask questions, and find out what it is exactly that you want out of paintball first, and then consider buying a marker after you've played a few games.
