I would strongly recommend a Kuan Ju Works M9 GBB (gas blowback) - $75 from
InfinityAirsoft. I paid $75 for the gun, $30 for an extra mag, $10 for a can of gas, and $6 for silicon lubricant.
I'm very happy with this gun - crisp blowback, great rate of fire (up from $25 UHC spring handguns), and I shot through both sides of a Cheerios box (as well as blowing a CD apart with one shot, range approximately five feet), so it isn't lacking too much in power.
I also have a Tokyo Marui Benelli Super 90 shotgun. It's heavily modified, but the internals are stock (can't really upgrade the Marui shotguns much, aside from tightbore barrels). I bought it used, yet it's still accurate to 80+ feet..even with .25g BBs.
It seems as AT airsofters diss UHC, but they actually make good budget spring guns - my first airsoft guns were a USP and M9 HW (both UHC). Shortly thereafter I purchased a UHC MP5SD3 - a solid little spring rifle. The Super 9 is generally regarded as garbage, though.
You may want to check some airsoft forums - here are a few to get you started:

I'm probably selling both UHC M9s, the Glock, and the MP5...
For dealers, check into Infinity (link above),
PlyconsArmory,
AirsoftToys, and
AirsoftAtlanta.
Generally speaking, you get what you pay for...the KJW M9 could be considered the Lite-On of GBBs, though
