You can get geared up for a bit less.
Cheap paintball mask (if you don't have one already): $40
Replica BDU's (since you don't plan to play a lot): $60 - $100
Used Boots (if you don't have a pair): $45
Tactical Vest (depending on used, quality etc.): $40 - $120
I don't own an AEG yet so I won't comment too much on those, but from everything I've researched and heard from experienced guys you don't want to cheap out on on this part.
What defines me is not what defines you. What drives me is not what drives you. I love what you do not love. I am me and you are you.
