Warped Water Pump Pulley

[BRL]

A few years back my SBC long water pump started leaking so I replaced it with a rebuilt one, at the same time I noticed that when I removed the original water pump pulley it had a chip missing by one of the holes.
So I replaced the pulley with a fancy chrome aftermarket one.
When everything was put back together and I started the engine the pulley wobbled and that caused an intermittent chirping sound.
I assumed it was the inexpensive water pump flange so I replaced the water pump with a better quality newly manufactured one.
The dang pulley still wobbled so that was the problem all along.
Just installed a new painted steel replacement pulley and that thing wobbles.
I wonder how many junk steel water pump pulleys are out there.
