How much does an RGB mod run ? Is the RGB mod reliable , or can the system be damaged ?
If you do it yourself, the mod would be pretty cheap. The components to complete one would be just a few dollars.
As far as reliabilty, it really depends on the construction, but for the most part, even a simple one would be quite reliable.
Damage to the system would only occur during the mod, if proper care was not taken. On my US TG16, theres some much room to work with, I can't see how I could mess it up. (Done the region mod, and that is far more involved.)
