Good call on all of that. I, too, have bought some rather odd pieces I probably shouldn't have. Sometimes, it's just because it's new and I haven't touched that mold yet (I'm not a completionist). But really, it's when we have 4-5 versions of a character that I wonder if we shouldn't sell off a few. I should probably sell off my Energon and Armada stuff first! :lol Those molds are pretty ancient! BW stuff I'm more attached to for being so different.
Have you thought about selling some of your collection? I'm doing that now. Not just for the wallet, but for the space! :lol Just hard to decide what to sell... which is why I'm selling periphery non-TFs first.
