I think all 3 are worth getting although Hello Nasty has some pretty bad sibilance. I haven't noticed any issues with any of the other records yet.
I fell victim to thinking these were limited and no longer available so I ordered a sealed copy of Check Your Head from eBay.
It ended up being one of the copies that included a 7 inch from the Beasties personal collection but also came with a second copy of the third record in place of the fourth record.
I later on came across the King's Road site and ordered all 3 hoping to repeat the luck I had with CYH and get another 7 inch. I didn't get another 7 inch but all of the records were correct.
Considering their cost, I say it's worth getting all 3. For what it's worth, they all came with the "limited to 1500 copies" sticker on them.
Sclemmer got a reaction from OneThreeOneTwo in Beastie Boys - Collectors Editions vinyl for $59 a piece
