I have a Oneway Talon chuck and love it. It comes standard with the #2 jaws which work well for everything I've turned so far. Some sellers include the adapter.
Compare prices at Rockler, Craft Supply, Woodworkers Supply, Hartville Tools, and eBay before you buy. It's on sale at Rockler and Hartville has a promo through the 15th that includes four free turning DVDs.
