Train Buddy, It wasn't hard at all actually. Kind of like cutting out paper dolls. (good practice in case they ever haul me away;-)
It REALLY helped a ton to be able to actually see it's size and height in 3D. I've never tackled a $200 list, kit before and it helped me to get familiar with the parts and up the courage quotient. My old approx. corrugated box cut out didn't tell me what I wanted to know.
I have a learning disability that prevents me from reading maps upside down for instance, so the "real deal" made all the difference. The "Wow" factor is there too for visitors until I finally get around to building the kit.>P
If I'm going to be able to use the shed at all, I'll have to cheat by not using the Walther's base and change the track spacing. It may include a turnout though, so not too likely :-(
