Where is the best place to buy Chesky, Sheffield?

I want to get into more of these audiophile cds. Do I do it directly on line with Chesky, Sheffield? Is there a less expensive way to go? Used? Feedback most appreciated. I mentioned Chesky and Sheffied, but am interested in any or all audiophile labels. Thanks in advance.
If you haven't already I would suggest you try elusive disc at www.elusivedisc.com.

I would also look at www.classicrecords.com as they have a great selection of both records and CDs.

Have fun!
And there is also Music Direct, with a wide selection of both CDs and vinyl.
