I have the GSG92 version sold by Cybergun that came out first in 2012. It is the exact same model as the Beretta, just different branding. Bought mine for $99.99 back then.
Fun to shoot. Feel pretty dead on to the real deal. You will get about 3 good mag dumps before you are out of CO2. I highly recommend you buy three or four extra mags and rotate mags after each mag dump so they can warm up a bit in succession.
Mine shot low and left, so I replaced my rear sight with an adjustable one. Had to JBWeld it in place.
