The blue Prime is a KO and it typically sells with a KO of the DIA armor. The face is one of three it comes with; it's a KO too probably. The head looks somewhat shallower than a legit DIA Commander, so it's likely it's a KO.
I have the blue prime and KO DIA armor and it's the worst money I ever spent. The Prime is floppy and that door piece hardly ever stays up, even after thickening the hinge with glue. The armor falls off the prime easily and it typically needs modding in order to fit decently.
The Sunstorm, however, is worth buying. I've seen KO Seekers go for $30, but I've seen them go for even lower. Mine has some problems, but there's no regreats here for buying him.
The SG Junkyard may go higher then $60, but I don't typically buy Botcon. $60 seems pretty low, but you could try it. Typically he sells with another two Junkions, so maybe breaking that up may make him worth a little less.
