All the FE boards were just unmounted, or downloadable from his website they were never an actual board SK wise or old school mounted just plain and simple print on paper . So if NKG are selling them they are PDF printed on paper and you are being ripped off .
Well, Noble Knight is selling the Budapest Pack, which has Boards 1 and 2 in it, not selling the boards alone. But yes, the price is much too high. Anyhow, I am pretty sure the boards that came with the pack ARE just printouts of the VASL boards. They are not great quality.
Printing out the VASL boards on two sheets each of cardstock will get anyone exact reproductions of the maps that came with the pack. And yep, he did several boards in addition to those two. All of them were available to download from his website last time I checked.
