My recommendation... Wait for the 6 tuner unit to be released then put one of them in the main viewing area and Mini's everywhere else. The 6 tuner unit should have faster hardware and the Mini software should be fully realized by then. Also invest in UPSes for every room. I've had dozens of TiVos over the last 13 years and only two failures. But all of my TiVos have always been connected to a UPS. Power fluctuation are the enemy of electronics.
