I'm a fan of airsoft to. It's super-popular here in Hong Kong. Here's my little collection...
I'd thoroughly recommend Tokyo Marui for all round performance and excellent quality. My MP5KA4 is relatively small and with the 200 rnd hi-cap mag I have (not pictured) lasts a good while. It's one of the louder airsofts though due to the short barrel.
As a secondary, I'd recommend the TM Sig P226 gas. It's a real cracker!
The Sig and the P90 are my friend's.
My fave is my PSG-1 though!
