We've got it...and I dont have any major complaints. The only concern, is that it does lose its signal from the satellite in rain/snow. Dish Network also dropped Fox Sports, which is kinda annoying when my illini are playing on it.
Dish Network also offers local channels, which could be good when you are mobile. Of course you'd pretty much be limited to one city's market unless you bought extras. But if one was going to be chasing mostly in OK, then having access to Gary England might be beneficial.
It's just hard to say how helpful it could be. I now have Dish Net in my home, after giving up on my old C-Band big dish in 2001. I was thrilled to be able to get my local news and weather again, something I had not been able to get with the old dish.
But yeah, I value my locals far more than TWC, since the coverage is more intense and limited to one general area.
