Cutting the cable, lets talk options and media setups

This is pretty much what I hope to accomplish.

So between Netflix, HuluPlus, Amazon and an HD antenna, I shouldn't be missing much in the way of hit series shows or non-ESPN NFL for >$30/month.

Seems that between Netflix, HuluPlus and Amazon there would be a lot of crossover, wouldn't one be the odd man out?

Also my kids seem to be fussing about missing out in Nick and Disney on their bedroom TVs. I need a solution for this.
Just FYI:
Re: streaming The Disney Channel.
From the research that I've done, you can get Disney through Sling T.V. You need Roku or Chromcast to get it though. It costs $20 a month. Also, they have TCM for $5 extra, if you miss the old classic movies.
Also, if you have a PS3 or 4, you can get PS Vue. It's a little pricey @$40 a month, but I hear it's one of the top streaming websites. It also lets you run up to 3 tvs at the same time, whereas with Sling, you can only run one t.v. at a time.
I myself have only Netflix at the moment. If I feel we need more than that, I think I will get Sling TV.
