Are any of you current Voom customers formerly customers of Dish or Directv? I'm wondering how picture quality compares to them both in SD & HD. I currently have Dish Network HD with 811 receiver(numerous problems) and also had SD with Directv. I'm considering switching to Voom when my 1 year commitment is up. Is each receiver monthly fee $9.95 or just with the $0 upfront deal? Thanks.
