How much money do you have to spend?
Personally I wouldn't bother with it or "World Of Morrissey", and would just get those 2 CD single boxed sets which came out a few years ago, and the "Dagenham Dave" single, none of which should be too hard to find second hand. (Unless you want another copy of "Jack The Ripper (live)".)
Whilst "My Early Burglary years" has a reasonable tracklist, it's still missing a few "essential tracks", and overlaps a bit with a number of other albums. Plus, those singles boxes look real nice, and you get all the original artwork.
But if money's an issue, it'll do. But you'll probably end up buying those singles in the future anyway.
