Thanks for the leads. I scored a couple of out-of-print CDs I'd been looking for at Academy Records & CDs (W. 18th), and found some cheap vinyl at Downtown Music Gallery (E. 5th). Other good, but pricier, stops for vinyl were Finyl Vinyl and A-1, both on E. 6th. For the best deals, though, you can't beat the guy on the sidewalk on E. 8th, opposite Cooper Union.He's there "three times a week, when I feel like it."
