Just a quick note to all pinsiders,,i purchased a Bird of Prey mod from these folks for my ST/pre,and i didn't use it right away,but 4 months later,when it was installed by my tech guy in Sacramento,it didn't work,AND all i got from the Mezels was "mod not returnable"!! They wouldn't even look at it if i sent it to them at my own expense, and i offered to pay for everything,reply,"mod not returnable'so be aware!!
