You can make (or have them made) wood arrows that can be just as consistent as alum or carbon. The last set I made for myself are all spined 74# and weigh within 6 grains of each other and shoot like darts.
I get the shafts from RMSGear and do the rest myself. I've made my own dip tubes from PVC, cresting machine from a drill and surgical tubing. I splurged on the woodchuck a few years ago for nock and point tapers because it's fast and easy.
If you're paying $55 for just carbon shafts, you won't be spending any more money on making your own wood arrows.
