There a reproduction pads from BE&A that are very nice and cost about $200. It's on a steel core, not a crappy glass core like some of the earlier repro pads.

I know that nice original pads were getting in excess of $200 before. Now with a good repro pad, no chance those parts are going to garner those rates any more.
Just dashes is a rip off at $450 for an A body pad IMHO. There are others that will recover a good original core for about $200-250 and they look great.
