Caved and picked up Cesium, and now that he's in hand I'm glad that I did. I never acquired the original Scoria, and picked up FT-04X during a sale. I like him a lot, but he sticks out like a sore thumb while on the shelf with the rest of the gang. Cesium fits in much better. That being said, I'm confident that I'd have been perfectly happy with Scoria considering my wishy-washiness about pre-ordering Cesium (assuming the quality was on par with my FT-04X). Cesium is great though, don't get me wrong. No real QC issues other than the common loose wrists; I actually had more problem with one particularly tight finger that refused to fold up during transformation at first. He feels great in hand, and looks real good in both modes. Lament the lack of ankle tilt though. I recommend Cesium to 1) those who don't have Scoria, 2) those whose Scoria had sizable issues, and 3) those who have the means and want a little something new. Happy with your Scoria? Excellent; I have no intention of selling mine. He's going to live with MP Grimlock on another shelf (I have Grassor as well, by the way). Save your funds for something else cool if Scoria makes you happy; otherwise Cesium is pretty darn nifty!
