Did you see this thread:
Shamadan for sale
Although it looks like that one's been spoken for (about 5 times thus far I think). I wish ones like that were more readily available - I wouldn't have had to have gone through all the trouble of making mine, plus having 110,478 dancers begging me to make THEM one just like it every time I post that picture!
But casing thrift stores is an excellent idea on many levels - you just never know what will turn up. Mine started as a thrift store find - $8! I stood there for half an hour trying to figure out how I could make it work as it wasn't an easy conversion of the type Tahiradancer was suggesting (and I suggest it too!). I finally had to tell myself "Zorba, it's EIGHT BUCKS! Buy the damn thing and figure it out later!"
