I've got a dealer offering me a Lazer HP 44" 19HP Kawi w/ mulching kit for $6500.00(tax already included) It is brand new(2 hours on it). Is this a good deal? What would be the approximate resale value for this unit around the end of the season. I'm not sure how many hours I will put on it this season, so give me examples for varying hours used and resale value with those hours. Thanx a bunch!
