Beginning airsoft question?

Hey i'm not to sure if i want to go and buy an airsoft gun and start airsofting. I love airsoft but the closest thing i can get around where i live is having 2-3 friends over and having a little skirmish. I have an airsoft gun already but its a pulse m72 and its kind of crappy. It has about -100 fps and only holds 50 bbs which lasts about ten seconds. If someone knows a good quality cheapish aeg then please leave me a link. I found a really good one that I like which is a full metal cyma ak74. Its over 120 though and my parents won't let me spend that much money on something they don't know i will be able to use that often. Which they're right. they will probably let me get something around 80-90ish.
