I believe that they are model kits, so that ebay seller has had them constructed and painted up first, thats a bonus, I'd hate to pay that much for a figure then stuff it up with my painting (lack of) skills.

Wheelie is a work of art, and his small size makes sense, Cyclonus has always looked a little small to me.

Powerglide looks very interesting,as does the Ironhide and Octane figures.
