I have Thundercracker and he's superb. Many others on here have that mold.
Definitely a must have, even in only one character.
This, IMHO, is better than trying to get them new right now, as the old versions of the first set have some flaws (beside TC, but even he has some) and don't have the best colours.
These have cartoon colours and have metallic paint. I recommend this set if you don't have any of the mold yet.
