As mentioned above, Kleiber is worth getting for the excellent #5, but by itself, #7 isn't my top choice.
My favorites are (in no particular order):
Guido Cantelli/Philharmonia Orchestra/EMI 7243 5 68217 2 9
Klemperer/Philharmonia Orchestra/EMI 7243 5 667952 2 8
Furtwangler/VPO/EMI 0777 7 69803 2 4
Furtwangler/BPO/Music & Arts CD 4049(4) - part of 4cd set of wartime (WWII) recordings. very driven and intense performances, use with caution =)
