They look good. Keep us updated on how you like them. Before I lunge into the trekking pole crowd, I decided to go cheap as well. Those Walmart ones were too expensive for me, so I just went to a thrift store and bought some old ski poles that were the right height for $3.

I haven't weighed them yet, but I am sure yours are way lighter.
I've taken a vow of poverty. To annoy me, send money.
