There are several good sources for new vinyl (mostly re-issues, but some new material too). I like "The Elusive Disc" (http://www.elusivedisc.com/) and "Acoustic Sounds" (http://www.acousticsounds.com/).
For used vinyl, there are many sources -- do a search of the Internet using the "Google" search engine, and you'll find several hundred. You might start with "Just For The Record" (www.justfortherecord.com). Garage-A-Records (http://www.garage-a-records.com/) is also a great site for replacement styli, record cleaning machines, etc., and they have a section on their web page for LP's.
