I have bought a few incredibly great pressings from http://www.better-records.com ...but they are absurdly expensive. The few I did get are my personal "must have" records, Jefferson Airplane "Crown of Creation" and a couple of Rolling Stones albums. I have also gotten some jazz and classic rock from sellers on Amazon, but I am selective about who I buy from. Likewise, I have also bought pristine collections from eBay (a Beethoven collection and a large tranche of classical records). So far, I have not had any issues.
edit: I have also bought from/or been given collections from friends and relatives. So far, the best pressings I have are from better-records ...except for a few from my started-in-the-60s collection.
