The problem with the SP for me is that your hands get cramped after a few hours of playing with it. The problem with the orginal GBA is that it has no backlight, so its hard to see in the dark and looks bad in general. To fix that, I've thought about taking the screen from the GBASP and putting it on the orginal GBA, so you can have the backlit screen and be able to play games comfortably. There's lots of people that have done this, and they seem very happy with the result.
Everything seems pretty easy to get except for the adapter. The only way to get an adapter seems to be from a Chinese man who hand makes them. The delivery time is about a month and I don't really want to wait that long and I already know my parents won't let me order something from china. So I'll have to find a way to do that.
Anyways I thought you guys might be interested in this project i'll probably be starting soon. There's plenty of other people who have done this before and their results look fantastic. Heres some of those people:
