No, they are not. I currently pay Voom $64/month for about 5 hours of TV/month, is that economical? Not to me. OTOH, I pay Dish $10/month and watch about 40 hours/month.
Even if Voom had PQ equal to HDNET, I would not pay them a dime more per month than I currently do, I just don't watch that much TV.
I'd rather spend my money on other fun stuff, like taking my daughter to the Zoo or somewhere else cool.
