I know it's far, but if you ever get out to Lubbock, the local record store, Ralph's Records, has a "warehouse sale" every Saturday. All the records are $1, and I've found some good ones. A lot of the covers and some of the records are in poor shape, but there are some jewels to be found. If you're up for hunting around for hours and have a good back (many are stacked on the floor), I'd recommend it.
