Being it’s taking me forever to build my layout,I thought i might speed things up by getting some pre-fabs and build-ups. I got a Walthers and WS build up. The look ok, but difficult to detail the interior. I got a WS pre-fab which is 4 assembled walls and parts. I left that one alone. I went back to kits,DPM,Walthers and some others and will eventually get it done…that’s what the hobby is all about.
