I know what you mean. I have Animated Lugnut, Snarl, Swoop, and Cybertron-mode Prime. It's really easy to pick additional neat-looking figures to buy, but so far I've been able to resist. The fact that I have no space for them helps a lot.
Plus, I'm trying to cut down on my spending. I'm pretty much focussing on Universe 2.0 and Henkei going forward.
