[GD-General] Free downloadable isometric tilesets?

[Brian H. <ho...@bo...>]

I'm trying to find some tiles to prototype a simple (2D) isometric 
engine, and unlike sprites or 3D models it seems that there's a tough 
time finding iso (2:1, diamond map) art work out there.

Anyone know of a good resource (cheap commercial or free) suitable for 
this?

Thanks,

Brian
