But either way I am right now working on some mods for the sansa's.
Right now I am working on SansaV2 and Fuze. Mostly fuze because it is REALLY different from some others that I saw. The fuze has signature checks which may cause reduction of performance. These signature checks are nothing but an annoyance to the average user. What is even funnier is that the signature checks are IN the firmware. So they are really pointless if you want to install custom firmware (say rockbox.) Right now I am simply experimenting with Sansa Fuze firmware components.
