The whole reason I brought up sphere maps is because I was offering to turn them into cubemaps for anyone. I only posted a few examples of cubemaps, but if someone wanted to have reflections of something other than a desert or run-down city, they would need to make their own cubemap. But, like you just said, few people understand cubemaps, let alone how to make them. So, if you give me a regular environment map (aka sphere map) I can turn it into a cubemap for you so that it will work with the shader.

A cubemap is a series of 6 images, compressed together. These 6 images represent the 6 sides of a cube. If mapped to a cube, the cubemap will create a seamless environment. Here's an example of what the above sphere map looks like once its converted into a cubemap. Also, an image of the cubemap applied to a cube and a sphere. Please note that this is what the uncompressed cubemap looks like....you can't actually use it in this state.
