I used to own an IMI Mini Uzi.
It is an acquired taste.
Make sure you try one out before you buy one, particularly if you are going to shell out the money to buy a real IMI.
I didn't like it at all.
Pros:
-Very easy to take apart and clean
-Looked cool
Cons:
-Sights were crude
-Extremely heavy, for a 9mm
-Grip safety was a pain in the rear
-Very heavy action spring with a very small cocking knob was difficult to do in a hurry.
