Remember those turn-of-the-millennium days, when wannabe DJs dropped $1,500 for a pair of Technics and a top-end mixer? They're so over. The recession version is buying used decks from craigslist, then taking your gear to Quality Electronics in West Hollywood. They'll clean, oil, tune and recalibrate each turntable for $29.99, making sure your wax is tracked with precision. While you're there, pick up some used vinyl, or go digital and buy the store's hottest-selling item — Serato Scratch DJ software. Yeah, even though Quality's been at it for 26 years, when there was nothing but vinyl DJs, it's just about the most knowledgeable place in town when it comes to the digital and analogue tools of the booth. Quality has remix software, production gear, and a deep stock of old-school headphones and cartridges. "I never disappoint the guy who needs a needle," says Israeli owner Yoni Hazzout. "I have them all." Prices are competitive. They know you go online. But you can't get that deep knowledge from a Web site. With strobes, speakers and fog machines for sale, there's a disco patina. 7761 Santa Monica Blvd., W. Hlywd. (323) 656-2475, qualityelectronics.net.
