The cost is very little to make one as long as you have all the tools. Materials were not very costly but I did have to get some new tools. I found a B&D Jigsaw for $20, sandpaper was around $3 for 5 discs, Dremel grinding wheel $5 for 5, and my stapler crapped out so i needed a new one of those which was $17. Tool cost was about $45 but it is all stuff I will get much use out of. Materials for this project cost me about $22 so as stated above if you have all the tools its a pretty low cost thing to do.
