Usually this instrument played when ceremonial dancing. In ceremonial dancing, usually only man play didgeridoo. Play this instrument can help you reduce snoring. That statement is true, British Medical Journal found it in study at 2005.
This instrument very funny, like a big smoke. I never play this instrument before but i see many video on youtube. I think this instrument have an unique tone, like trumpet on jazz festival. This traditional instrument sale for 10-100 $ on ebay. Maybe it too expensive for some people. I think you can make your own didgeridoo more cheap.
I found one video tutorial to make homemade didgeridoo from pipe pvc. I think for make this instrument from pipe pvc you need less then 10$. If you make this instrument from trunk of tree, its too hard if you want to make a hole on the center of he trunk. It's simple if you have wood tools, and your trunk of tree not crooked.
