In case it isn't common knowledge, the color choice is normally the cost determining factor, I had some stuff done in Prizm Silver, which is silver with rainbow colored flake in it, the powder itself cost over ten times than the black, it was bitchen though (it's on my freinds quarter midget frame). We have an oven and the gear here, it's cheap to do as a DIY if you have the tools, mine is small so big stuff like trailers have to be done down town at the shop, it should cost about half what it would cost to paint it...
