Thought this was cool: RARE TRANSFORMERS ROTF 35MM TRAILER NEW UNUSED LOOK!!! - eBay (item 260392329961 end time Apr-18-09 21:38:07 PDT)
These are cool; I have several from TF1. I'd definitely encourage people not to get excited and pay more than $10-$15 for them though, as they'll pop up with some regularity down the road a bit.
