Yeah, you noticed that too!!!!
From now on my customers get blank replacement bats unless they specifically ask for the now twice as expensive W bats.

If it's Mad Amusements I just bought out their stock of white bats, they still have yellow ones. But now that I looked PBR has them for sub $3, D'oh!

If the Stern rebuilt kits seem like they are priced high then rebuild the flippers smarter.

Here is the cost of a stern rebuilt kit
$45

Here is the cost if you buy just the parts you need

2 coil stops $4.25 each
2 plungers with links $3.95 each ($2.75 each if you buy the nearly identical Williams ones)
2 hardware with bushings $1.50 each
2 coil sleeves. $.55 each
2 flipper springs $0.75 each

Total is $22 ($19.60 if you get the williams plunger)

The flipper pawls never break or wear on Stern flipper assemblies. Half of the cost of the flipper kit is these 2 pawls.

The EOS switches and switch actuators you can also buy separately if they happen to be broken.

Just remember that you really really need to replace the hardware and bushings that hold the plunger link to the pawl, stern doesn't use a shoulder bolt on these so the threads on the bolt get worn down first before even the plastic flipper link wears.
