The newer Bones and Deepcuts lines have these and reasonably inexpensive,
I picked up the cemetery set and I like painting. It is a very nice terrain set.And those are great, if you paint them yourself. But I don't like painting miniatures, and I'm also not very good at it. I prefer to have them pre-painted.
There's been two excellent sets that I recently acquired: Dungeon of the Mad Mage has some awesome laboratory props, and there's an amazing Pathfinder cemetery set as well.
Otherworld makes models for orc and kobald tribes, women and children.
I always want more miniature furniture: Doors, bookcases, tables, chairs, fireplaces, chests, barrels, crates.
