I was honestly disappointed by my interaction with Steve, I was all worked up when I called the first time, thinking that I was going to get abused and told to "look up the part number and maybe he would take my call when I called back."
None of this happened, he was nice and helpful. He told me most of the part numbers I looked up were wrong or not available anymore and told me the correct number or substitute.
I have given up looking up part numbers before I call because I know I will screw it up or that number is long unavailable. I make sure I know the correct standard name for a part, but that is it. Though I am sure they would still take your order if instead of saying you needed a "flipper pawl", you said you needed "the thing that attaches to the flipper under the playfield".
What makes PBR great is when you need info that a big fancy website does not have listed with the parts. I wanted to convert the linear flippers to standard style on my EBD, I was not positive what I needed to replace. Steve did instantly. Order placed, no problem, not even any abuse given to me for not knowing part numbers.
