I am looking for a place (or many) where they sell this musical instrument. I miss the one I left in my country.
I’ve been using my vacuum cleaner pipe. Bit high pitched, but any port in a storm…
B&Q, plastic plumbing pipes … or Australia … 
Why don’t you hollow out a piece of the thick variety of bamboo. There’s lots of it around and it works great. The best way to knock out the nodes is by using a suitable length of reinforcing steel (steel rods used to reinforce concrete),
Hope it helps!

I don’t have the time, the material and the skill to make a didjeridoo by myself. What I am looking for is a place where I can buy some.
