I've built three racks with this product, and am in the process of building 5 more.  With six Wolmanized (chemically treated to resist rot and insects) 2x4's (about $9), a few lag bolts ($6), a hand saw and an electric drill, you can create a rack that will take years of abuse and hold an amazing amount of firewood.  Time to build a rack...less than 30 minutes!
