Exactly Angus. Don't waste your money on this rip off just because it's collectible unless you want to take your chances and resell it on Ebay to make your money back and then some. If you own all those albums already there is no point.
Now if they took all their severely limited edition b sides, rarities and covers, remastered them and put them on a double CD set, that would be great and something we would all want. You could even have some snazzy Mackie artwork included. But like Buzz says, the world is not perfect. You have to settle for crappy, expensive 7 inch rip offs and whatever else you can find on Ebay.
