In the states your going to have more avaliblity than uk europe for these, or so it seems, I've a oldish pair of CTI braces which i dont wear often enought. see my mini-adventure thred for what i mean.
i looked into the Asterisk braces about 12 months ago, sizes, fitting even tried some and did everything short of putting my money down and walking away with a pair. For me those where the dogs dangle.
have a look at whats out as some of the companies have come up with some new stuff in the last 12 months
