I've been wanting to build an IC for a few weeks now based off of this design, but I've been hesitant due to price of the copper. I know many of you use http://coppertubingsales.com/ but the $20 shipping just blows it for me. I've checked HD and Lowes and their prices are a little expensive. Anyway, I called up Naughton's, which happens to have be directly across the street from HD, for a copper tubing quote. 1/2" x 50' refrigeration tubing cost $45.95 + 8.1% sales tax! Much cheaper than coppertubingsales.com. Plus I got some great help from the staff there. Over all a great experience.
I guess the moral of the story is, if you're looking for copper tubing on the cheap, take a trip to your local plumbing store.
