Flashlight + Rkcstr + heatsink + Time/work + batteries/holder + lanyard + solder/tools... Not $20 for the kit, sorry. Perhaps I think my work is a little more of value than some of the other builders here. Also, this isn't my only job. Im a welder and work long hours during the day, so 2-4 kits a week is plenty fine for me. Also the other side projects I do for people here.
Its the kids who's only job is to build lasers and price them to sell, that make my price seem high. I feel my product is worth the price. I choose to set my product to a higher standard. You won't find jayrob kits much if any cheaper. I see it this way. If people wanna go cheap then they have their options, they can buy from darkarmyofone, after all, he has all the time in the world to build kits.
