Here is a great web-site from whom to buy SACD's
http://www.amusicdirect.com/
Go there, load SACD in the search engine and it will list all of their SACD's available. They currently have 770 SACD's listed for sale, plus other Audiophile quality recordings. I have bought from there and they do a great job. They ship fast, their prices are reasonable, they e-mail you with the tracking number. Check 'em out.
