I have a TiVo OTA, so I would drop locals, but I also have the Welcome pack, so I would probably have to up to the Smart pack and then drop locals. I do not watch Dish locals at all.
I've owned a Tivo almost as long as I've had a satellite. Since the first 10Hr Tivo was introduced at CES!
When I changed to H3, I had a Tivo premiere in my Master. I've been paying $13/mo for years with Tivo; The OTA Tivo just came out, and when my current box died I was going to switch to it, or the Channel Master version.
It can do streaming services; but my internet is to slow to do much.
I loved my tivo, but at $13/mo for just OTA I think I paid to much for it (yea I could have done lifetime; but for me the life of a box is about equal to the same as the monthly payments) so I swapped it for a H3 & Joey. (now kinda wishing I still had it for these disputes; I wasn't thinking that the H3 didn't have an OTA option like my old box did)
It's easy to use, I think the new ones even have commercial skipper (mine didn't).
You might find a bargain on ebay; or Tivo's refurb bin (my last was a refurb, over 3yrs old when I sold it)
