It also depends on if Shaw is fully digital in your area. I had Shaw service at the same time as Starchoice a couple of years ago and while there wasn't a discernible difference on the digital channels, on the analogue SD channels, there was a huge difference. Blow that up on a big screen tv and it'll be even worse. i know you're primarily interested in HD, but there will be times you watch SD. As far as storm outages, in 10+ years with starchoice, the only time we've had problems is when there's been snow on the dish.
