Trover, your ignorance is showing. Doosan is Bobcat's parent. Just because they don't have a name familiar to you does not make them bad.
Also, there were lots of value brands back in the day. John Deere was a value brand in the tractor market (they started out making plows). That is until they got better at making tractors and marketing got better, too. The vast number of brands helped to keep prices down. The big two are actively working to imply that other brands are junk because they like the higher margins they get from the reputation. Once more people realize that most tractors are well made, they will not pay the premium.
