There are so many that I have heard are good but have never had the opportunity to play. That's why it was fun a few years back when you could always find non-working projects for $200-$300. It usually required a shop job but was a low risk opportunity to try something new. Those deals seemed to have dried up for the most part.
Visiting a collection like Tom Taylors is a great opportunity to play a bunch of great EMs. The trouble is there are so many it's hard to stay focused.
