Just received my first GBA in the mail today. The condition is excellent! I never owned one, mainly because it launched right as I was getting married and quickly had kids after, so... yeah, no money. I owned an original Gameboy back in the early 90's and one of them was Tiny Toons, to pick this up again is a huge rush of nostalgia, I love it. I look forward to revisiting the old and playing the games I missed.
If you like the SP, you should hunt down an AGS-101 backlit model.
