PBR has been my go to for 7 machines, em and ss,williams,Bally,Gottlieb.
I like their parts, especially their rubber.
Send an e-mail, the package comes amazingly fast. I send a check.
There has only been one item they couldn't supply. They recommended a Gottlieb part that would work on a Williams, it did just fine.
I like their flipper rebuild kits and pop bumper rebuild kits.
My problem is I can't find EM projects, at least not this year.
I would love to send Pinball Resource an order, I miss the experience.
Never called them though and had the pleasure of speaking with anyone, always e-mail.

When the power went out in Town a line of customers waited outside a little country store to get food, propane and supplies. Why? He had a mechanical cash register.
There is a NAPA store here that does not use computers, still by catalog and cash. Everyone goes here instead of the Advance Auto. Why? Price and he always has what you need.

Just two examples where old school is still king.
I will always buy from PBR if they have it.

Its been said Ems will be still working after an EMP attack. You will still be able to buy parts for it through PBR.

Just a heads up, my orders used to take 2-3 days. The Mail is is so backed up my recent PBR order is going on 2 weeks. Not their fault, but I am waiting and checking Tracking and watching the mailbox.
180 buck order, by e-mail, no hassles. Submitted it on a weekend, shipped the following Tuesday.
