There has been alot of discussion on these on this forum: Gardenweb.com (click on FORUMS, then TRACTORS). They seem to get good reviews for the money. I plan on buying either the Scotts 17.5/42 or the Sabre 17.5/42. Same machine, I may go with the Sabre so I get good service from a local Deere dealer. Make sure you have a "participating Deere dealer" near you before you buy from Home Depot.
I have heard good things, nomatter who you buy from.
