Best is a opinion, but I prefer the UTG M32 Master Sniper Rifle, It Has 430 FPS and Costs $80 Without Scope. I bought mine From PyramidAir.com With Scope, Bipod, Sling, and Extra Mag for $120. The best Airsoft sniper by power is the Green Gas M700P Sniper Rifle Competition Modle, 720 FPS For $200 From Hobbytron.com But no one will play with you if you are using it.
700fps or more is illegal without license its considered a type two weapon and you can get in serious trouble--not recommended.
There is really no best airsoft sniper rifle, because there is a lot up to personal preference. All ARES sniper rifles are very good, my personal favorite being the MSR-004 because of its unique bullpup design. If you are looking for a semi automatic sniper rifle, the Reals Sword SVD is one of the best ones out there. There is also a large range of very good M14 sniper rifles and tons of bolt action ones in all price ranges.
The most expensive.
no, it doesn't

If the gun is spring then it is most likely not automatic but if its electric it is most likely automatic.
an Automatic Electric Gun or AEG is am airsoft gun that runs off a battery to fire bbs instead of being hand cocked or powered by a compressed gas.
Nerf gun
Automatic Electric Gun - i.e. airsoft toys guns.
Try a sports store
Usually, the only non electric rifle this is also automatic will be CO2 powered.
tac r71 ..... cheap expensive-rrr.... -> CYMA Ak-74 all metal
In airsoft guns, automatic electric gun. Battery powered airsoft, versus spring powered or gas powered.
The best airsoft gun you could get for $150 would probably be an Aftermath gun, but you could get a JG M4 or M16 for under $150
