I would say go oldschool and go for a mech automag or old cocker (if you can find one, just make sure you run an expansion bottle. As I find when you go punter hunting with a 'bling' gun that customers always whinge that you have a better gun, where as in reality it is still just a mech! so I would say an understated 'mag or cocker. So at least you can turn around to most of the younger players and say "well this gun is older that that there tippmann or inferno you are using"
