Purchased in early 2006 for over $6000, have receipts. Will sell for $4500. Barely used, excellent shape. Had built into our pool last year, but we also have the on-the-deck moutnin gsystem as well. Adjustable speed (super slow to too fast for most swimmers, and everything in between). Feel free to contact Paris or Renee at 936-856-0873 if you have other questions.
