Keep the Classic RI on your list.
Led Zeppelin – Led Zeppelin II – Vinyl (200 Gram, LP, Album, Reissue), 2005 [r1125994] | Discogs
I found one for cheap (in OLD downtown Bakersfield,CA 15 years ago? )before scoring the RL. If you never heard an RL, the Classic is quite good.
Comparing the 2, whole lotta different. Not "better" but to my audiophool ears, bass, drum impact of the RL more convincing.
