Advice on a new gun

Unfortunatly i am limited to only $100 , so i've had my eye on the JG Ak 47 thats 380 to 400 fps. or Is there another gun out there i can get?

Trust Me...just save up your money.

Definitely save your money.
If you're hell bent on purchasing a gun I can't remember where but some place online was having a special on the JG AK47 Beta.
There's also the Galaxy MP5k and DE Ump. Again these aren't great "omg I need to run to the store and check the weapons out" types of guns, but if you're on a budget and are hell bent on getting a gun ASAP then these are some decent choices.
But again I HIGHLY advise you save up more money.

or u can always check on craigslist and get real good aegs for the right price....

Craigslist is a good suggestion. At The Moment im Saving For A Magpul licensed classic army m4.

thats a nice aeg..i got a magpul already...traded for my kwa....but just the body on my magpull is worth well over 400...and i got it of craigslist..as well as my echo 1 scar with upgrades...

Craigs List is pretty awesome, BUT I've heard a few horror stories, so I advise you that if/when you find something you like you bring an experienced friend with you to check it out with you.

Also try AirsoftClassifieds.com and as much as I dislike them check out the AirsoftRetreat Classifieds also.

dont focus too much on FPS

More FPS does not = better gun

jolly green is right.. look at tokyo marui for instance.........
