Weak Ankles, Anyone know where to get a good wobble board? Any other advice?

Hey guys, due to a long series of injuries brought on by various problems i have fairly weak ankles, and im looking for a wobble board, i bought one from sportsmart and the thing sucks so bad, its like standing on the ground, no difficulty whatsoever. So yeah, my question would be, does anyone know a place online where i can get a good wobble board for less than 60 bucks, or does anyone know any other good ankle rehab exercises? thanks

Right off the top of my head, single-leg Romaninan DLs and reverse lunges come to mind as components of a successful exercise prescription.

Perform Better has a ton of stability equipment.
