Technical Anyone Use American Muscle Car Patch Panels?

Looking at patches for my '54 chevy and these guys came up on Ebay and they're only a couple of hours away from me. I know EMS probably has the BEST panels, but was curious if anyone has tried theses guys.

Those are made by Schott and the feedback on Schott panels isn't good.
I think American Muscle buys from here, there and everywhere though. Seems like I have one of their pieces on my watch list but from another and far more reputable mfg.
