My new motto seems to be: If you're not painting, buy stuff! I'm not sure how viable that philosophy can be financially in the long term ("not very?").
I recently picked up a few aquarium pieces at Wal-Mart, and then bought a few more through Amazon, which just arrived in the mail today. These should all work fairly nicely as ruins on my fantasy battlefields.
Scale-wise, I think they're perfect for my 28mm minis.
I probably need new terrain like I need a hole in my head...
I'm not sure how much I really like some of the brighter colors on these, like the lemon yellow pharaoh here. I may end up repainting some of the louder bits in more subdued tones.
These pieces were not terribly expensive as far as prepainted scenery goes. All were less than $20, some as low as $10. But I still may have to put a clamp on the purchases soon.
