If you play Dwarfs, you best come with some war machines and lots of them!
I have the latest incarnations of the stone thrower, and some older bolt throwers but I need more!!! Today I stumbled upon ZVEZDA that makes some VERY affordable war machines that don't look half bad. They are not quite as detailed as a GW product, but I think a few dwarf bitz here and there would do the trick nicely. The stone thrower looks very similar to the last edition Dwarf one. The bolt Thrower just needs to be chopped down so the stunties can reach.
At $15.00 for 1 Bolt thrower, a stone thower, and 3 wheeled shields (use for entrenched?) How can you go wrong?
