I recommend saving up a little bit. You'll regret investing (because that is) in a cheapo AEG. New G&G start at about 260 + taxes + shipping. The Classfieds here on ASC has many good deals (new or used) at reasonable prices.
Not anybody understands it the first time.
After getting a good ol' TM as my first AEG, I'm thankful to myself to have made the best choice, 'cause it still rocks hard!
The only way you would regret a quality AEG, is if you should quit the sport after a few games.
