I picked up a broken SP off ebay for $12 shipped, and got the resistor and wire from radio shack for $6. Everything else I already had around the house. It took me about 2 hours to complete and I was surprised when it turned on and worked the first try!
You can play it in pitch black, the picture makes it look weird, there are no dark spots like that, and the light is much more even. It does seem to have a bit of a "optimum viewing angle though"

And even in low light it is good:

Its a huge improvement over how it originally was, and I plan on doing the same mod to an original GBA once I find a nice clean white model.
