Since I got injured a few times this year I see the value of having one (also, my girlfriend is tired of me trying to practice on her--a common experience, I assume). I'm trying to get over the weirdness/creepiness factor of it. Side note: I wonder if AI will soon enable us to create a highly realistic grappling dummy the way we've done with sex dolls or if that's too dangerous? Also, side note, I do love the idea of being able to say "I'm going to go play with my doll now" and make prolonged eye contact with whomever I'm talking to. When I DID have dolls as a child I use to violently beat them against my tree house until their heads rotated all the way around. Yes, it's a good thing I found jiu jitsu. Anyway! I've just gotten over the psychological hurdle in real time, I think. The monetary hurdle is tougher. I can't justify spending a ton of money on something I won't use much. So, is there one that is affordable? That allows you to practice a variety of techniques? That I can store in my (walk-in) closet and so avoid terrifying visitors to my home? What models are good? Should I just not bother? Can I rig something up myself? I have so many questions. Help.
