Calm Before the Storm is frequently on ebay. Cant help you on the other 3 though, because I'm in the exact same boat. Just make sure you know the difference between OG and represses before making a purchase, cause the differences are sometimes really subtle (especially with the rapbay represses of The Worst and The Worst 2k)
I wouldn't even buy em cause you aren't supporting Strange or Tech by doing so. You're supporting the record label that fucked him over.
i can more than likley get all of em thru my work
