Recommendation: Sabbat (JPN)

I think it's safe to just stick with the full-lengths mainly, then grab Sabbatical Holocaust, And The Sabbatical Queen, a live album or two, and a few splits, and you should be fine. Chasing after the dozens of limited press vinyl EPs would bankrupt Oprah Winfrey.
 
Woah I'm suprised at how many people don't know Sabbat. That's not an insult, just an insperation for upcoming Reco's I may do with legendary bands like this.
 
From those mr Torsten carry, I think I'd recommend Satanasword for albumness and Sabbatical Holocaust for variety (Bunch of old EPs and stuff, completely asskicking but naturally doesn't have the album feel to it)
