Hi Rob,
Langley are in kit form and unpainted. I have no experience of the fairground stuff, but have built a large number of the road vehicles - they are a delight. They are white metal, and go together with the minimum of effort and look really good when finished. There are photographs of some completed models on my web site.
The buildings are a mixture of vac formed plastic, etched brass and cast components. I have used etchings and castings in otherwise scratch built structures and they are of the same high quality as the road vehicles. Have no experience of the vac formed stuff.
Regards
Richard
