Edit: Ouch on the price of the vinyl, but I agree - rare vinyl is worth it. I paid $100 for a mint copy of Steeleye Span's "On Tour", an Australian only release. I have been enjoying it for a while, but they finally re-released a lot of the tracks on compilation albums.

If you want to do that level of archiving, you might just want to rip with EAC (highest possible quality settings) and then compress the original, uncleaned, unedited to FLAC. Share the FLAC as a lossless compression. Then clean and compress the way you want it.
