Here's a color scheme for VS2005 I had created a few months ago but had not published before (I think). Ragnarok is another high-contrast scheme with a dark background, with two variants:

Ragnarok Grey - download for VS2005 | download for VS2008

Ragnarok Blue - download| download for VS2008

Both are using Consolas, 15pt, but feel free to change them (they would definitely look good with Damien Guard's Envy Code R using the italics-as-bold variant). I personally think the blue version looks better, and it is actually quite usable.
