StressVest

When paintball just isn't enough anymore but you don't really want to get into the habit of shooting real guns at your buddies — while being shot at, no less — then perhaps it's time to invest in a StressVest ($2,500 and up). Developed for training use by police and military personnel, this high-end version of laser tag delivers either a vibration or an adjustable shock that gets worse with each hit and tops out at 4,500 volts via a specialized vest and a crazy laser insert that goes into a REAL GUN and emits a laser burst every time you pull the trigger. Sure, you've got to register for a federal ID number to own the thing, but that's totally worth it for some realistic weekend warfare, right? [Scouted by Chris]
