Saw this at Sears, guy said it had been there for 6 months. I estimate maybe it is on 12 hrs per day for 180 days, like 2100 hours of use so far. Regular price is like $1650. Their warranties are $440 for 3 yrs and $660 for 5 yrs, I figure I have to get a warranty for a floor model, but those sound super expensive. Anyone have any advice?
