I got some Tomshoo trekking poles from Amazon about 3 years ago for under 15 dollars each they are still going strong for me.Im sure this has been covered previously, but I just tried out the Cascade Mountain UltraLite carbon treking poles. $60 from amazon. They are nice and light, the locks didnt slide even with putting all my body weight on a single pole. Only annoying thing is they have a vibration/slight noise resonance when you put them onto the ground.But for the price and weight Ill keep using them.
