In Miami there's no shortage of cool, retro shops. Blame it on all those estate sales and wealthy retires. Still, the vintage collection at Visiona stands out for its ever-changing selection and affordable prices. A few years back, local vintage stores charged extravagant prices for their wares. But with the advent of eBay, these joints have learned to compete. And Visiona, which specializes in authentic 20th-century furniture, is the place to fully appreciate and try out the great designs of the past 60 years. There's no old junk to be found here. All the items in the store's crammed showroom have been selected for their vintage authenticity. Genuine Saarinen tulip chairs, which sell new for $1,200, can be found at Visiona for just $350. While knickknacks such as Panasonic's space-age Sixties TV sets can be had for $200. The store also offers plenty of lamps, sofas, and old design books.
