you appear to be very lucky in your location, all UHF stations, all roughly in the same magnetic compass direction and all 30 miles or less. There may be some terrain issues with the blue/violet ratings. A good quality UHF antenna like the Winegard PR-4400 or Channel Master 4225 should work well.
If you prefer the yagi style antenna over the "bed spring" type, than a Winegard HD9095P should work nicely.
I have used a refurbished Samsung SIR-t451 for about a year with no problems. Like all digital ATSC tuners, it does require a preset level of signal strength (threshold) to receive anything at all on the digital channels, therefore a really good antenna, mounted well, is required
