you could talk to Khell Sennet [http://www.escapistmagazine.com/profiles/view/Khell_Sennet]. I know he's quite the paintball enthusiast and could probably give you some good advice.
Someone say my name?
Aha! Paintball. The fine sport of shooting people you like until they no longer like you.
Well OP, three things I'd need to know:
Do you intend to play Woodsball or Speedball the most? Woodsball is where you have plenty of cover (woods or not), and at the start of the match, may not actually know where your opponents are. When it comes to shooting, Woodsball uses much less ammo because usually Guy A gets the drop on Guy B. Speedball is the flipside. A big open field, some obstacles (most often the traditional inflatable kind), but you know where everyone is at all times because it's still just a big open field. Rule of the game, shoot until you hit someone.
Do you know what air supply is available at your local ranges? CO2 is the standard, HPA (High Pressure Air) is common and overtaking CO2 in availability/preference. Nitrogen also exists, but I know fuck-all about it, and most ranges don't carry it. Why it matters? There is a piece for most markers called an expansion chamber, which if installed, improves how CO2 works, but prevents HPA. If you intend to use both, a marker without the chamber would be best. If you KNOW you can get HPA, it's the cheapest in the long run, and better than CO2 any day of the week.
Budget. Gimme a price range (and indicate what currency it is in), and I can usually price out things pretty damn well.
So those are my questions. If too impatient to answer and wait for a reply, my idiot-proof advice is the Ben Tippmann "BT-4" basic marker (also called BT-4 Combat). I used to advise the regular Tippmann line as good, but reports coming back on the last couple years' models say otherwise. The Japanese company that bought them have replaced all their guts with plastic, and now they break so damn easy.
