One of the cool things about martial arts is, they're inherently minimalist and frugal. At least, most started out that way. For example, the Okinawa farmers, kobudo weapons like nuchaku, sai, tonfa are adaptations of farm implements. When I first started, for striking targets we had foam pads, cut in squares, layered, and tied together with a belt. We'd use empty anti-freeze jugs for kicking targets. Jhoon Rhee's "safe-t-chops" were a novelty, most of us used what was little more than an elastic sock with a thin piece of foam in it. Equipment has come a long way, but you still don't need much of anything beyond sparring gear unless you're into fancy uniforms. What had changed is membership in a club- I priced out some a while back, the MMA gyms have gotten expensive.
