Im about to start giving a guy guitar lessons. He has offered me a like new "saiga 12" stock furniture longer barrel model that has been broke in. He said he was thinking $500 for the gun... im charging $50 for 2 hour lessons weekly.... so thats ten guitar lessons in 2 & 1/2 months/10 weeks.. Is that adeal or should i just take the cash? I like the saiga 12... but i was also wondering if i might be able to trade one for a 7.62x39 AK or even an AK pistol??
