There's also the Bernhard Haitink cycle on LSO, available on both CD and SACD. They sound great, and mostly they're potent performances. Very hyped here in Europe right now. I'd say they're a great buy, they're cheap!
The Klieber 5th and 7th rules, but the SACD is very average in terms of sound quality. The LSO Live series is probably the best out there. The Pentatone series is right up there, too, and they are sufficiently different readings so you will want both.
