I have an extra backlit SP with a broken screen and cracked shell. I know that probably doesn't help, but figured I'd mention it in case you wanted something cheap for a fix-it-yourself project.
The main guts are in perfect condition, so it would work to replace the guts in a GBA SP with a good screen and good shell, but broken guts in some way.
