[Disclaimer: I may, from time to time, be a seller of this set.] First, to address the previous review, I imported copies from Italy in July 2011. Since one is going into my personal collection I opened that one and checked the discs - I had no trouble playing any of the discs I tried, and I specifically tried the first 2 discs (Oberto) and had no problem playing them even on a portable, Walkman-like CD player. So whatever problem did exist does not appear to be present in the current Italian pressing.
In general, I find this a simply outstanding collection that includes not just the operas but also the Requiem, the Songs, ballet music and alternate preludes not included in the opera recordings, the Four Sacred Pieces, the movement Verdi wrote for the aborted "Requiem per Rossini", the String Quartet and almost 2 discs worth of "discoveries" recorded by Riccardo Chailly (who is the conductor for the works below from No. 31 - on, where another conductor is not specified). If it is not every note of Verdi's music that has survived, it's darn close.
A few complaints - there is no English translation (on the other hand there is a book - not a booklet but a BOOK - of the Italian librettos). Although most of the operas with alternate versions have been included, the first version of Simon Boccanegra is not, nor is Les Vespres Siciliennes (the original French version of Vespri - however, in this case, I believe the musical differences are minor). The version of Giovanna D'Arco included is from a 1951 radio broadcast that has always been sonically problematic - it has been cleaned up sonically here, but it is still is FAR below the sound in the rest of the set. On the other hand, it IS a thrilling performance with the young Tebaldi and Bergonzi in radiant voice. The only good modern recording of Giovanna is on EMI and I guess they refused to license it. Some of the versions choosen would not have been my first choice, but none is without merit.
But some kudos are in order. Though Universal has a Falstaff (by Giulini) in it's catalog, they obtained the better-sung RCA version under Solti and also obtained the RCA Vespri with Martina Arroyo and Placido Domingo. Both the St. Petersburg and La Scala versions of La Forza del Destino are included, and both the Solti 5-act Don Carlos (in Italian) and the Abbado 5 act French version, with appendices, are included. They have included the better-sung (and harder to find) Del Monaco -Tebaldi Otello under Erede in preference to the more famous version under Karajan. I would have preferred the Sutherland-Pavarotti-Horne-Wixell Trovatore (although I already had that one and didn't have the Banaudi-Pavarotti-Verrett-Nucci version that is included, so that worked out for me). But the latter Trovatore appears to be uncut, while the earlier version suffered from cuts and tinkering by the prima donna's husband.
If you don't have most of these recordings, this is a no-brainer, to get all Verdi's works in one box for a little more than $4 a disc is a great opportunity. But even if you have several of the operas included, some of these can be hard-tofind (and expensive) at present - for instance the Oberto and the Stiffelio.

I have no hesitation in calling this a great set (and no one but Universal could have assembled all the operas in such fine performances) - whether it is worthwhile for you will depend on how many of these recordings you already own and how deep your pockets are.
