Your price for materials is really based upon what you use, where you buy it and if you substitute parts. It also depends on how elaborate you want your product to look. These parts listed are what I used and are just recommendations. I am sure there are some short-cuts that can be taken. Remember any electrical components substituted might change your resistance values.
