I don't think it's worth it
I dunno, you ever played a gba sp? its priceless
I've played a Gameboy Advance SP version, but the games always were too high for my tastes even back in 2007 when I got mine it was $250USD and all the games were used and above $20USD a piece, Now. that eBay seller obviously purchased that GBA in the photo for $80USD and is asking for the price of a used car, WTF?
to me it looks like it was resealed, and that asshole probably is just some rich scalper who makes a living off other peoples products, I have no respect for such a person, who probably just wants to go to Los Vegas and gamble or proustite the money anyway.
