I decided this weekend to pick up the Hailfire Droid. It's pretty cool, and a little cooler than I was expecting, actually, since its rocket firing mechansim is a little more controllable than I was assuming it would be. It's fairly zippy and powerful, though the wheels have little traction to them.
The Clone is a very VERY plain white Clone with virtually no decoration on it besides black on the visor and bodyglove, making it I guess sort of a variant paintjob.
