Exactly, but when you add $100 on to the price of the hubs for anodizing, you are in phil territory.

I have tried doing it myself with a homemade version of this with supplies I borrowed from school one summer back in my days as a high school teacher. Of course, the quality of my setup probably wasn't as nice as what you could acheive with the kit here, but instead of paying $260 for a kit, I paid $0. My results were extremely mixed. I did a stem that came out really well. I did a set of handlebars and another stem that were OK, but not great (color didn't take very well) and I did a crank that completely sucked.

Some of the chemicals are not so nice, so it is good to have proper facilities - again, working in a school has its pluses.
