Well, all HDTV receivers from Dish Network and DirectTV have OTA tuners built into them. So you'll get OTA with them when you get their HD packages.
I don't know about D*, but I know that E* will require you to get their HD package if you get one of their HD receivers as part of their "sign up" promotion. You could always buy an HD receiver on eBay, but why pay that much when they're willing to eat a lot of the cost to sign you up.
Dish Network has better Picture Quality and more HDTV channels than DirectTV. But you might find D* cheaper.
