I have found quite a few pieces from GreenLight and M2 Machines in the stores over the past month. And with my recent trip to California I was able to grab quite a few more pieces from my diecast distribution friends at http://www.collectablediecast.com to add to this post. Quite a few are really old which I was lucky to get from collectablediecast.com.
