I have this one from amazon
Hand-fired Modern Didgeridoo - Beeswax Mouthpiece - Easy Player! https://www.amazon.com/dp/B0087HEO64/ref=cm_sw_r_cp_api_i_.7HxBb2DC4554
It’s $30 & looks like wood but it’s some kind of synthetic material and has a very good sound and decent back-pressure. I’m getting pretty good on it and am about to upgrade to a professional didge next month but I highly recommend this one.
Didgeridoo (plus Amazon Smile!!!)
