Does anyone have any comments on the Hustler Walk-Behinds? They seem very expensive. The 54" isn't much more expensive than a 37". With other companies, there is usually a bigger difference in price between a 36" and 52" for example. Is a 37" Hustler Hydro Walk-Behind worth $5,200.00 plus the cost of accesories? Also, do they have floating decks or hour meters? Thanks for the help guys!
