Fagan's been around forever, they date back to the days when most antique collecting was done by dealers sending out catalogs every few months. That being said, you still have to know what you're buying, for instance -
Modern lion's head kukri that sells for the 10's of dollars through other dealers can be yours for $475 -

Wouldn't class this as a fine kukri, it's a standard import/export knife of the late 20th century -

Old ads for these, most date post WWII, and don't go much farther back than that -

Frontier knives, lots of mistakes here, if you know butcher/kitchen knife manufacturing, design, etc.... history, you should be able to spot the mistakes -

As always, do your own research, and buy the knife, not the story.
