Here's some stuff I found a little bit ago... It was only like $10.00...
I've fooled with other options in the past... like the ones I listed, but I like the black... If I get it to work, I'll share the 20'+ extra I will probably have with everyone if they need some. I think its made of a poly-ethalene since its for drainage... so should be alright.
