im new to paintball but ive been doing whole lot of research.
One of the top balls for your buck is Xball Gold, you can get it as low as 45$ a case (2000) at Actionvillage.com, normally its around 50 to 55. Step down to Xball Silver/Bronze for bit cheaper price but not as good.
For a nice solid ball thats not as pricey but not as good check out DxS Rec balls. at close to 25$ a case

A quality ball between those two is Diablo Heat at around 35$ to 40$ a case.
Remember the better the paintball the better the shot. =)
Hope this helps.
