Harmonica holders

I need a harmonica holder and want to buy one online. I have tried any out in real life so do not know much about them. I know its a cheap purchase, but I dont want to buy something that has an irritating flaw.

Can anyone recommend something? or tell me if there is something I should avoid?

If you're talking about a neck brace harmonica holder I highly recommend the Lee Oscar unit.
Compared to the old Hohner brace, the Lee Oscar positions the harmonica much better to your mouth.
