I decided to give these a try and bought some through a business that was selling them on Ebay. Star Fort Minatures based in the UK. I ordered one building. It came in a flat box and after looking at the model on the website I finally figured out how to put it together.
I was so impressed with these buildings I ordered 3 more! below are 2 of the 3 I ordered.
If you would like more info on those MDF buildings have a look at this company's website:
They have since migrated off of Ebay for sales and you can order direct from their site. Their service is good and they communicate with you when the order is shipping. Overall a good experience.
