I believe they were imported for about 10 years (don't quote me on that)- they were banned in 1989. They are definitely neat looking, and will get attention at the range-but they are nothing great to shoot. I would get one to collect, if I were to buy a pistol (had a Uzi A carbine, sold it).
These days, I have seen them for $950-$1200 NIB- as a matter of fact there are a few right now on Bowers non NFA board- they are around $950 (one is LNIB, the other is NIB). The reason they aren't $2000-$2500 (like the mini Carbine) is that Uzi imported quite a few pistols (where HK imported something like 3000 SP89's)- which is why they go for about $2800. Hope this helps.
