I bought the dyes directly from StewMac, they are very good and deliver fast.
The finish you want doesn't look too difficult. Mind you I have never done it, but I would stain black, sand off and stain medium grey. Then clear coat.
You have to test on scrap pieces until you achieve what you're looking for. Grey is somewhat easier, because you only need to deal with black dye and different concentrations in water.
It's not unlike the guitar in my previous post, that's a double stain in cherry red, with a second stain really saturated. With black I would go with a lighter second stain, but again you need to test on scrap pieces.
A few drops of the concentrated stain in 10cc of water is usually enough for a guitar top.
