What gun?
contact your local gun store.
It depends on which gun and what shape its in. In general, about 50-80% of the price of a new one.
How much do you want to spend? Anywhere from $35 to $3000+.
There is the Thundergun(Upgraded is Zeus Cannon) and a new freeze gun, a.k.a. death to zombies I don't know too much about it.
More cost effective to buy a new one.
Depends on how much you need it. Not like New York tho. Get a fiend to check the gun possession laws there. If you have a friend that you need to keep the gun around for - get rid of the friend.
You can buy a new Triton paintball gun for around 90 dollars, but you could also try buying one on ebay or amazon for a much cheaper price.

Contact a local gun dealer.
