VeriProx

I am interested in acquiring some biometrics, and i am wondering what the masses think about Northern Computers, VP 1000, veriprox fingerprint verification. Just wondering if there are any problems from actual users or people who have heard about it. spefically the wait time associated with it. If there is a cue of poeple waiting to get into the building how long will it take them, i know the veriprox website say i second, but is that accurate in the real world.
