The one right at the front with the blue windows is around $10-12
The other four though... Oh boy! The cheapest one is $80 and they go to about $500+
(Although they technically aren't Rodimus...)
There is Classics Rodimus (far right)
Then Henkei Rodimus (JP release of Rodimus)
Henkei Wildrider (JP black recolour of Rodimus)
Botcon Shattered Glass Rodimus (convention exclusive black/purple awesomeness)
