$18.69 and free shipping for my country (france).
I have also the first gb boy with the gb color case.
The new one is realy better !!
Work with any buzz/noise (no need prosound mod) with EMS 64M USB and Drag n derp.
Brightness can be adjust or cut off the brightness to use outdoor with sun.
Use battery (bl-5c) with a charger.
the gb boy have a link port but I haven't tryed.
No bug with the vibrato like the first one.
The case is not cheap, it's not a nintendo but any bad plastic noise when you touch it.
Now I need to test the battery life
