I Just purchased the Proform treadmill model # 770 EKG at sears a closeout for $589 and had a 15%off coupon and I'd like to know if I should buy the warranty! I have 30 days to decide and I was wondering if anyone had any problems with this brand! I was reluctant to buy the warranty because the sales person kept telling me that I'd be better off with the Nordic track which was $600 more! I'm sure you get what you pay for but I didn't know to trust her or not because she makes commision! I just wanted to get home real quick and get on line and ask the "real" educated crowd that I know and love!So if you could kindly shout out some opinions--or your experiences with the proform---I'd truly appreciate it!Your friend in fitness--Francine
