I have a few of these packed away, I do have 1 on display in my SW office now,
I got into these a few years back, some are very cool and can be had for a decent price, like most vintage items, some are expensive and hard to find, Also these offer prototype enthusiasts a ton of offerings of unpainted and alternate painted figures, many introduced items can also be had, some of the more expensive items from the line are the 4UP prototypes, I'll get into those in the vintage section when I cover prototypes in general.
