I'm assuming its the unicorn style? You do know why it broke? The spacer was missing in the clamp gap.
Many have tried or said they have tried to fix a broken one. I've never seen or heard of one fixed. HondaMan also ays in his book, they are unfixable.
You'll find good used ones go for $150 and up. If you get one for less consider yourself lucky. But eBay usually has a selection, and you may find someone giving one up for cheap.
many threads on that piece. It is no longer available from Honda, was only used in a few model years, and one by one they get broken. So scarcity is pushing the price up.
