Shooting Illustrated has a review of Century International Arms UC-9 carbine. It looks like an Uzi from outside, but internal mechanism has been redesigned so it can only be fired in semi-auto, and shoots from a closed bolt.
Due to internal redesign, field stripping may be a bit more complicated than the original Uzi, but at the price of $750, it is nothing compared to a real pre-86 Uzi.
