What's the one TF that you most regret buying? Mine is a problem fixed, as I sold it with a bunch of my collection last year, but it was Armada Super Base Optimus Prime. I was actually anxious to get that toy, but when I finally got it, transformed it, looked at it... "What a piece of crap!" I thought. I still took a loss on it when it sold, but even to this day I still regret buying it. Anyone else?
