SP why do yo want o know/
Because we want to know what factor made you choose the SP over the other one, was it price, was it availability, etc...
Your opinion counts.
What Darkk was hinting at was that one word/extremely short replies are frowned upon. If the question is basically an opinion question, don't just give your answer, justify it.
Anyway, I'm still using my original GBA, which I paid $100 for when it first came out. When I heard about the GBA SP, I definitely thought it was cool, but the new features in no way justify spending another $80-100. The graphics are exactly the same. There's no games you can play on the SP that you can't play on the original GBA. Sure, the SP has a backlight, which can be really nice, and it has a better design, but these minor
changes are not worth the money. Besides, I can think of better things to do with my money.
