Offbeat may not be the cheapest record store to come down the 'pike. Nor is it the largest. But if you ever happen to be looking for a strange, little-known album that went out of print a decade ago, this should be the first spot you hit. The store's music collection includes not only CDs and cassettes but also LPs, 45s, eight-tracks, and even reels. Yes, reels. Remember those? If anyone still happens to own a reel-to-reel player, which looks suspiciously like a small version of an early computer, this should be the only record store for you. And if you still have an eight-track player, well, there's just not much we can do for you. When you decide to join the 21st Century, there's good news: Offbeat buys old collections. The store hours are a bit skimpy (Wednesday through Saturday, 11 a.m. to 5 p.m.; Sunday, noon to 4 p.m.; closed Monday and Tuesday), but isn't a midday trip worth it for choice vinyl?
