the toy collectors who seek out every packaging/misprint and SKU variations possible.
Hah! One of the things I have in a giant plastic tub is a ridiculous collection of Star Trek the Next Gen action figures I bought back in the day (with a bunch of DS9, too). I really loved hunting them down... A million years ago I had each one pinned to my wall like some horrific gaudy wallpaper.
And I found a weird "mystery Data" at an Albertsons once covered in dust in their pathetic toy section that I seem to recall had a different arm than he was supposed to have.
I did get my Geordi signed by Mr Levar Burton back in 2006, though. I should probably dump the rest at some stage. They're pretty worthless. I did have fun finding them. I think the hunt and capture is generally more fun that the keeping forever.
