By my count I have about 20 discs (averaging well over 60 minutes) of Szell's recordings with quality mastering. More are available on Tidal. So if Sony released the box set now, I would likely pass.
For Szell fanatics (like myself) I suggest you explore the Japanese e-tailors. (I buy from CDJapan.) They have a number of titles. From what I know (which is far from complete) many if not all of these are remasters, superior to the 1990's vintage budget releases in the U.S. Prices are USD10 give or take (except, unfortunately, for the Beethoven which is on SACD and twice that amount), plus shipping, where they offer a range of options. A reasonable way to pick and choose a number of titles without breaking the bank. I also heartily recommend the budget Haydn box. And I like the most recent Great Performances discs (not the ones that look like newspapers).
Acoustics aside, my all time favorite Szell interpretation is his Schubert 9th (the "Great" C major), originally recorded 1959 on Epic lp, now on Sony cd (not his last recording for Angel/EMI).
Many of the 1980's Sony Szell CDs sound rough to me.
Some Szell favorites: Mozart PCs 21 & 26 w. Casadesus; Prokofiev PCs 1 & 3 w. Graffman; LvB Overtures, Sym. 9, PCs 3 & 4 w. Fleisher; Haydn Syms. 92 - 97; Dvorak Cello Cto., w. Fournier (DG); Mahler Sym. 6, DKW (EMI); Sibelius Sym. 2 (Philips); Walton: Sym. 2, Variations on Theme by Hindemith, Partita for Orchestra.
