buying new/used vinyl in NYC?

Here is The Village Voice shopping guide for music stores located in Manhattan, also expandable to the other boroughs.

Forget Stereo Exchange unless you're in the market for dvd player.Too sad because this was the store that got me hooked up on high end in 1992.Go a couple of blocks up to East 4th and Bway to In Living Stereo.They aare the same guys that used to sell audio in Stereo Exchange and are located in the original Stereo Exchange store.

Check out the Chelsea flea market or its sister on 76th street. (See http://www.footprintguides.com/New-York/Antiques-Shopping.php for details). As with all such markets, selection varies from week to week.

There are quite a few places at Saint Marks in lower downtown. If you want to sleap there is a great place in City Island in the Bronx. I need to get the exact name but I'll email you as soon as I find it. This guy only speciales in Vinyl and has thousand of records.
