I think there are a few of us out there in that boat.
When I sold my loose G1 Victory Leo and Star Saber it was around a year later that I just let out a great big NOOOOOOO!!!! About six months after that I was lucky enough to go to Japan and they were my two main goals, I found them and now I have two stunning, unplayed with, pieces of Japanese G1 glory :)
I missed the yay to nay part in my earlier post. My yay was every single Transformer ever made, to a huge nay, lucky all this happened before the movies but sadly not before animorphs :p Anyway, the collection has well and truly been updated since then with a lot of nays and me still having a roof over my head :D
