I just bought them today for the accompanying Ironhide and Nightwatch Optimus Prime they come with, and I already have the SS/BO molds. These guys are brand-new, not even removed from the packaging insert, still twist-tied in. Both yours for $5 or $3 each plus shipping, PM me your ZIP code for a shipping quote.
FWIW I have no feedback here, but some of you may recognize me from one of the other TF boards. I'm a stand-up guy, tho, honest!
EDIT- I now have a feedback thread here on Seibertron, FWIW:
