How does the newer stuff compare to the old?
I only have The Final Sign Of Evil which I understand is a re-recording of old material. I quite enjoyed it, great brutal thrash. I saw a double pack of some OOP Sodom CDs at Half-Price Books but they're over $40:

Just like the Whiplash they sold for a high price a while back, I'm hoping it's there long enough to get slashed in price.
