So glad to see this revived!
My gaming group in Berkeley played extensively with the Legacy pricing system. In fact, many of them never played with anything other! (Mainly because our group of 7-8 always played solely with my 'Scape stuff, and I instituted Legacy early on. Many of them learned the game with Legacy pricing.)
Our general opinion was that it may have been a bit conservative. I know others who played with Legacy felt the same. It didn't do quite enough to lift the bottom-of-the-barrel units up.
At some point, CornPuff produced a second, revised, version of his Legacy pricing, which he called
Legacy: Evolution. It was more radical. Probably a bit too radical.
So... I'm glad to see that you're starting with the earlier (less extreme) price list.
