You'll have to provide some more information; your playing style in
particular.  If someone answers you and says they have the "perfect gun
for you" they are fools.  The gun must fit the player's methods and
preferences in order to work for them.  Some things to consider:

- do you shoot a lot?  do you have the *money* to shoot a lot?
- are you mechanically inclined? (can you make minor/medium adjustments
  on a fairly complex gun?)
- if you need to hit someone, do you shoot a large number of balls to
  gaurantee at least one hit, or do you take time and line up on him,
  depending on accuracy for that first one to hit?
- are you able to "pamper" your gun on the field, or could it get knocked
  around quite a lot?
- if you get a "barrel burst", would you rather take 30 seconds to squeegee
  it out, or just expect the next 30-40 shots to be way off aim?
- do you mind carrying a marker that weighs more than average?
- do you want a setup that you can upgrade slowly, carefully choosing this
  and that option a little at a time, or do you want to get a quick start,
  with the "best" setup?
- if something happened that only allowed you to play once a month, would
  you still play?
- if you're on a team of five, are you -the guy in front, -the guy on the
  flanks (side), -the guy covering the back, or -the lone man sneaking
  in from the enemy's side/rear?
