I picked up an Aftermath Broxa and have put thousands (10 -15k) of rounds through it over the last three years and haven't had a problem. It allowed me to get into the sport but now I have upgraded to a TM M14. Some aftermath guns are good and some are not. It's a crap shoot, if yo are willing to give it a good, then realize if it breaks down no one will have any sympathy for you here!
Always try to buy the best yo can afford. Understand that if you get age verified you can pick up some killer guns from the classified section for not a lot more than a new Aftermath from Cabellas.
Nothing says loving, like a head shot!
