I'm kicking myself for selling mine a couple years ago. I really miss that thing. I don't care if it's loose, so long as it's complete and in nice shape. It will be given a good home amongst my TF Classics Autobots.
I have a Hasbro MISB R.I.D Optimus Prime as well as a Takara R.I.D Ultra Magnus for them to combine to Omega Prime if you are interested. Prices are in Singapore Dollars so you have to do a conversion to avoid misunderstanding. Here is the link. http://cgi.ebay.com.sg/ws/eBayISAPI...m=140215298938&ssPageName=STRK:MESE:IT&ih=004
