A word of caution from experience with kickstarters I have invested in and ones that friends have invested in: Yes, this may seem cheaper but this sets up warning flags for me more than anything. I looked over their kickstarter and this looks like another one where someone doesn't know how to count costs. I am going to call it now and say that this terrain will probably be delayed or even unfulfilled. Or it's made out of the crappiest mdf. Either way, I wouldn't trust it. The Black Sheep stuff is already low priced enough that I was a bit hesitant but he had a lot of people with fulfilled orders who praised the product and the producer.
I like those new pieces NP. If you don't mind telling me, how are you affiliated with the Black Sheep guy?
