No, i understand that you wouldn't want to trade for something that wouldn't cost a lot.

Really I was just making the point that, although the Uncharted 3 Explorer is scarcer than many Collectors Editions, along with say God of War Ultimate Edition and would cost in excess of £120 . . .those editions that I mentioned are just as hard to find but would all cost less than £20 if they turned up on ebay.

Probably because they are not as desirable or popular as the more expensive CEs.
