Hey, thanks! I haven't been here in a little while.
Your collection sounds awesome, I'd love to see some display pics.
Here's a fairly recent shot of my prototype cabinet, though it has changed since. I do also collection production items.
As for where I get them, it really is a variety of different places. From auction sites, to private collectors, and from shows to former employees. It's taken many years, and a lot of ground work on the whole. Thrill of the chase and all that.
