Purchased a 9.31 Brand Spank'n New! After about 3 weeks ( 2010) there is a squeal coming from the front motor housing...disappointing! I call the store where I purchased it and they suppose to be sending a tech out to look at it. The only complaint is having to waste my time coming home from work to get it repaired. The squeal starts at speed 6.8 and continues until 7.5. VERY ANNOYED!
