Although they can be tough to scout out, you can find them in the usual second-hand spots, from craigslist to antique stores to flea markets. Like any antique, prices can range from under $100 to several thousands of dollars. The 1950s two-tier tea cart from the top photo is $3,400 from Antiques on Old Plank Road. The aluminum-frame cart in the second photo is $1,600 from Modern Times. Another pricey, but beautiful, classic is Alvar Aalto's Tea Trolley. Less expensive versions can be found by keeping an eye out at thrift stores.
