Here are some interesting terrain pieces for gaming. They are available on Shapeways (SALSAG8R By Aaron Moyers). They are designed to be printed in Natural Colored Sandstone.
Lucid has a large collection of rules and miniatures for their various game systems. I happen to be a fan of their Toon Realms Elfs. A bit cartoonish and fun.
They also have a line called Savage Core that might fit in nicely with Copplestone's range. These are more realistic.
For the last 10 or so years I have been collecting miniatures for a Christmas game that has yet to be played. Earlier this month I scored a huge Chaos Dwarf army that was painted. I got it for $250. The cool part was the painted figures replaced all the unpainted Chaos Dwarfs I had collected over the years. I was able to sell 5 lots of them on Ebay for $260, meaning I got a fantastic painted army for free. :-)
Now I am on the hunt for some Nutcracker figures that would work with all the other figures I have collected.
In the search for all things Victorian Sci-Fi | Wild Wild West I came across a rather cool vehicle from the movie Wild Wild West called the Derailer Tank.
