What are good airsoft brands, as in looking to get a spring, bolt action sniper rifle for not a heckofa lot?

Not particularly, there are better brands out there. Define "grossly expensive". But here's my best guess for your unknown price range: http://www.airsoftgi.com/product_info.php?cPath=280_283&products_id=2493 (you gotta buy the bipod separate if you want it)

Ok if i were you id go with a Bar-10 or the UTG L96.....if u can spend more money somehow go with a TM VSR-10

For your purposes (assuming that you don't plan to shoot from much further than 100 feet away), a UTG rifle should work fine. If, however, you plan to play the game in a serious fashion, than you would be better off not getting a sniper rifle at all unless you're willing to spend the many hundreds of dollars it takes to build a successful rifle.

well all spring guns are really good and in my opinion UTG are the best spring rifles they are dead accurate to. The best bb's to use are .28 gram even though they dont go as far as others they hurt alot more and will hit ever target. Also the wind does not really affect them.

This gun is really good and pretty cheap http://www.airsoftgi.com/product_info.php?products_id=2127
