Ah yes, finding that perfect manny. I'm sure many of us on the RPF would pay big bucks for a fully adjustable manny, but they just don't exist.
I found these...looks like the shoulder and elbows move. Maybe a little padding on the arms, also looks to be split fingers.

I might try one of these.
howlingwind13...I've tried both this style for my Fett costume.
The first manny's arms are very flimsy. They'd also have to be bulked out a bit for most costumes. It is nice that they have that adjustable shoulder joint (a bid deal) but it's so flimsy that it won't hold a pose. The hands are terrible. You'd think that having each finger adjustable would be nice, and it is in theory, but the palm of the hand is super narrow so forget trying to get gloves on this hand. Terrible IMHO
The second link you shared was what came with my Fett when I bought him from a RPF member. It can actually be made to look pretty good. Since the manny is fiberglass it has a good body shape. Having the elbows jointed is very nice too, and they can be tightened to hold a pose pretty well. The BIG downfall to this manny is that shoulder joint. This means that you can't move the elbow AWAY from the torso at all. If you have a figure (Fett, Stormtrooper, etc) that holds a gun this is a BIG deal breaker.
This is what I used for my Joker display.

It's expensive, but does a lot of things right. The head can come off, giving you a great "neck" to add your own custom resin or silicone bust. The hands are great. Rigid wire inside the foam, very bendable and they stay put. Not quite perfect, but very close and the best I've found. The arms, legs and even torso is all bendable. I used this manny with a custom stand that was zip-tied to the manny itself allowing the Joker to totally stand on his own, so it was very sturdy. I thought about using this for Fett but I don't think there is any way you'd get this guy to hold a heavy weapon, that's his downfall (pun). The other great thing about an all foam manny is that you can take a knife to him and "skinny him up" as needed. This manny comes pretty muscular, so I had to hack away to get that Heath Ledger physique.

You can see from these pics that you can get some pretty accurate hand poses, the best I've seen really. I was also able to get hunch him over a bit to get that "Joker Hunch" kinda look going. The arms where easily adjusted after all the clothing was put on. Every time I'd walk by him it seems like I'd adjust him a bit. It's maddening!
hope that helps, keep the conversations going on manny's! :thumbsup
