Aside from the soldering iron, solder, marine goop, the needed "stuff" to do it, it cost about $170.

Here is my latest cam, with my first 3D camo job. This one is in a bigger case so it can hold extra batteries for longer life in the woods.
I haven't cleaned up the glass yet. But if you do self camo jobs, you can buy black cases for under 15 bucks and a tuble of Liquid Nail and some paint. Cheaper than paying for camo dipped cases for 25-40 bucks.
