Suspect anyone with an EM has PBRs phone and/or email handy. I always use email, wait for the response of 'confirmed' and have the check ready to send out as soon as the package arrives. One time I got a response of "call me, I have no clue what you are asking for", I made sure I had as much info as possible before I called, five minute phone call and I had the right parts on the way.
Agree with others, it is a rite of passage in pinball.
