A manufacturer of amazing depots, mine structures, and warehouses from the narrow gauge country (mostly RGS) in HO, S, and O is going out of business:

Ragg's...to Riches? is going to retire soon and so he's not planning to continue his awesome line of kits. Better get 'em while you can! I just ordered a Placerville warehouse in HO.
I can't say enough about how amazing these kits are. I'm really bummed they won't be part of the narrow gauge scene anymore. They directions come in a spiral-bound book and the parts are all numbered exactly sequentially to ensure a perfect build every time. Kits come with a plywood core and you build them up in layers. So far I've built his Placerville depot and his Ridgway depot and I'm really happy with how they came out. Just ordered the Placerville warehouse kit.
Best shingles in the business too!
