Has anyone had a look at them ? I might consider a purchase if the books are worth buying so any comments and observations on the quality of the research work and the sources used would be appreciated.

From what I've seen of them they look outstanding, but the cost is a bit high (especially if you want them ALL!). They have a Facebook page as well. Seems very well researched and illustrated.
