So? I got my GBA used, and it works flawlessly...even though it did come to me with a nice layer of battery acid on the back of the system. #-o
Once that was cleaned up, though, it's fine. Heck, even the screen came in great shape.
If you don't have a GBA, why not get this one? It's definitely cheaper than the SP, even if you choose to spend the extra $10-$15 for a light and rechargeable batteries, and it still plays just as well...
