A collection of all Gameboy Advance SP's available from 8-Bit Trade.
Both AGS-101 and standard 001 models are available.
AGS-101 is the superior (to most people) model with a brighter back-lit screen that can be switched between medium and high. The 001 model is the initial release of the Gameboy Advance SP with a back-lit screen as well but can only switch between "off" and medium.
Please note, if the shell only is pictured on this page, do not worry. Each product is hand made / made to order so this is just showcasing the color. The final product will be a fully functioning Gameboy as described.
