Well I got my SP in the mail today,and the super cool black one might I add,and I have to say I am impressed.It only uses rechargeable batteries,which are included in the system,so you never have to buy AAs again. The light is cool too,it works well in the dark but doesn't do to much when there is light out.The d pad is new,feels weird at first but now that I am use to it I like it better.The L and R buttons are small,but I haven't really used them too much and when I have they felt fine.
Overall it is kinda small but I have gotten use to it.It is great if you don't have a GBA but if you already do I would hold off on it,or just buy a light.
Well that is what I have to say,I would give it out of
