Went to a garage sale in my neighborhood, asked for video games and this all they had and I GOT THEM FOR ONLY $8 with the charger too!
The blue GBA SP has a big crack on the screen and it's not too noticeable when you're playing but I got it for $1
the Pearl SP is the 2005 model (brighter backlit screen - AGS-101 model) and it's the rarest and most expensive GBA of all... got it for $7 and I NEVER thought I'd get my hands on this for such a CHEAP price... they even go for $50 on eBay... It's f**king heaven I tell ya.... and they all came with a little game too.
Enjoy the SP's!
