Many thanks for the advice guys.
I'd not ask £600 odd for my AIA, but I would like to get enough to cover the cost of an Uzi without putting any more cash towards it.
Good advice about looking for a second hand one, I'd definitely consider it. Tech guy pm coming your way ;-)
As far as the MP40....one of the reasons I'm after an Uzi is because my wife used to have one when serving in the Israeli army and I thought having a pop with one now might remind her of her youth

. Owning a replica German WWII rifle wouldn't go down too well with her!
Cheers again, and I'll let you know what happens
