dang BullDog,where do you get all of this equipment that you pull apart and graciously share the results and information with us here?either you've got a very good job that allows you to have BD-Spending fund,or you have a CB shop locally with a bad or non-existant alarm system and a weak door lock lol just kidding.

really though,in the past couple of days i have seen more threads by you about a specific item that you've pulled apart and gone through and then shared your results here.that's pretty cool,thanks.we've got our own product review paned,BullDog-777!!!:thumbsup:
