My son is recently into Airsoft and looking at gear.

Hello all, I am a father of an amazing kiddo that is on the autism spectrum. He has found airsoft and is very excited to get into it. We have been looking at gear and it is quite expensive. Would there be any chance anyone has some used stuff around that i could acquire? I dont make much money and want to get him more than the cheapo amazon gear that already broke and some proper armor as he probably could use extra protection. I found the guides and am steering him in the right direction for the next time we can purchase something. Thank you all, what an excellent community you have.
