Came across this the other week on eBay.

All 3, no mention of being KO's and specifically says Impossible Toys, for about $36 posted.

On a quick search I couldn't find out if these had been KO'd but a comparison between what I received and google images of the originals makes them look identical. They arrived within about 10 days of ordering too.

If you were after these 3 then definitely a good purchase. I am very happy with them.
