Thanks for this thread about the 515E. I hope to check our local Costco this week...praying stores here in MN have it. I've been looking at ellipticals for a month now, and have yet to find the right combination of features, ride & price that will suit both me & my husband. We were planning on trying a costco membership anyway, so this is great incentive to get in there & check it out!
Treadmill Doctor.com stated that Costco had some sort of customer satisfaction guarantee, that really "backed up" the lesser warranty on this particular model. Can anyone here clarify what that is/how it works?
