Try pet stores? I've had good luck in both the fish reptile tank departments; for a while, here in my locale, the big box stores had an assortment of 'jungle huts' and foliage, along with area/culture specific temples and buildings. Lots of South and Southeast Asian stuff, as well as Meso-American, and usually pretty reasonably priced. I tend to get mine on clearance, when the stores get ready to 'flip' the product lines. My two-story resin 'village headman's hut' is from this source.
