Best Beef Jerky

Hey guys!! So I went last night with my dad to 7-11 here in NJ and he bought a pack of Jack Link's "Sweet & Spicy Thai" jerky. He LOVES beef jerky, but last night it was really tough and he ended up just throwing it out after spending $7.00 on a small bag!! For Father's Day I really want to pick him up some REALLY GOOD jerky! Can some BOTL point me in the right direction? I myself love beef jerky, but don't know much about the good stuff!!

Thanks!
