The FS420e is a better value at 1199.
xTerra is a product line from Dayco, builders of Spirit, Espirit, and Sole products sold primarily through Costco.com. xTerra is the new brand name they obtained to move to the mass market category independent of Sole Fitness. The product is classic Dyaco: solid quality at a reasonable price. Although priced the same as Sole they don't give you the same feature for the money.
