Rarest TrackMaster Trains

I have a fantastic idea! We all ought to get together on some sort of call or live chat where we can take all the rare tomy/plarail/trackmaster items, debate them, then order them based on rarity, and there could be two seperate categories, rarest plarail/tomys and rarest hit toys/trackmaster lists. of course with many of us living in different time zones and regions around the world it would be difficult to organize, but it could be done. I have a few ideas about placement of items myself.
