Northern Tool has them. As far as reliability I can't say much other than a business aquaintance has one and says you have to be somewhat mechanically inclined. Nothing major just little things here and there that go wrong with it. The problem is you want to get a task done and you get half way through it and it breaks down. Keep in mind this is coming from a business aquaintance.
As far as I know they are renamed Chinese Jinma tractors. From what I've heard, like Murph said, if you don't like working on them some... they might not be the tractor for you.
