Hi Keith,
This is just an idea -
Maybe you could list the braces you've already tried and those you've had recommended to you. It's possible that people here could tell you their experiences with them, good or bad, so you have some idea of what to expect.
But, you should also bear in mind that even if a brace has been recommended to you that you haven't yet tried out, you shouldn't necessarily disregard using it just on the basis that someone on this board didn't get along with it. Quite often it's a very personal thing and you ahve to find one that suits you, both with regard to comfort, purpose and cost.
Let us know what you and your parents decide.
Take care,
Laura x
