As for the Dungeon alternative? Now there is a company selling pre-built treated wood cabins and storage buildings. They can be bought via rent to own or outright. Delivery to your property is free. Prices seem real good to. Sure wish I'd have had that option back when I was renting the dungeon. The one below has a loft also.
If any of you are interested let me know and I'll get Ron's number for you.
You can also visit the manufactures site to get specs and so on.
Also on a different topic you might want to watch this short video from CNN. I guess they are finally getting tired of the BS to!
