The Uzi rate of fire is really fast. If you dump a mag, most of the casings will be still in the air by the time the mag is empty. It's a lot of fun, but be aware that it has a different firing mechanism. The bolt stays to the rear and fires when it comes forward after you pull the trigger. So be careful when clearing malfunctions b/c it will fire if the bolt goes forward, unlike many other guns.
Is it an indoor range? If so, suppressed might be nice. I've fired a 10" M16 indoors, and you (and everyone else) can feel the concussion wave. It's loud.
There are a lot of cool guns on that list, though. You really can't go wrong. If ammo cost is a consideration, then you may want to avoid the more exotic calibers as the range probably makes you buy their marked up, expensive ammo to use in their gun.
