Seriously, yes they are worth the money. I don't currently own one, but have picked them up and seen them in action. The majority of my continental models are Marklin 3 Rail, Marklin have mostly cast metal locos, but Hag locos are also all metal, and seem to weigh about twice as much as the Marklin equivalent. They do items in both 2 rail and 3 rail digital and analogue.
Their models are generally regarded as more accurate and to scale than, for example, Marklin. I certainly have some on my radar for when we win the lottery tomorrow night, sorry folks, but it is my turn this week, but then I will stop playing!
