ok so from what people have told me on here my tumbler has gone bad. i know its not a big deal but its pissing me off. can anyone help me figure out how to replace it or point me in the right direction. i dont want to just go taking stuff apart and screw something up. also where would be the best place to find one cheap. i have now idea how much they cost. im assuming i could get one from a part out on here or from morad. any other better places to look? thanks.
