Good textures and tutorials on the website. Fairly good value for money. However - as someone who has designed paper models in the past, I question the value of never using paper tabs in construction, but relying on thick card and gluing the edges of cards - while it gives you a neater edge, it dramatically increases the difficulty of putting together a model. Paper tabs do need to be accomodated in the design, but can also be used as a method of spacing for interior placements of items (IMHO).
On another note - promoting the use of photo paper for the colour textures is all well and good - but the gloss of the paper makes it very slippery. That'd be okay if you had a method of securing the walls and items to the floor and not just to each other - as it is, I can see that moving miniatures around is going to mean continual adjustment of the objects on the map when they get bumped. How about thicker card and slots for the floor as well?
