Does anyone know anything about when TiVo will have Roamio Basic power supplies on sale? Or at least what type of power supply can be used as a replacement? I have a Roamio Basic coming to replace my Premiere I use for OTA and that I also use it to carry content to my GFs house. So I need an extra power supply to keep at her house. That way I just need to carry the TiVo over and nothing else.
