Steve,
The Daisys and Winchesters are made by a company in Turkey. The Quest is made in China and the Legacy is (supposed to be) made in the USA by Crosman.
Haven't tried any of them so I can't tell you how they work. I have a Gamo Shadow of which the Quest is supposed to be a copy of. If the Quest is as nice as the Gamo it should be a fine gun. Also Crosman customer support is something to consider. It has a reputation of being far better than Daisy or Gamo. Had I not bought my Gamo when Wal-Mart closed them out at $74, I'd have gotten a Crosman gun.
