I don't see that much benefit of getting the built-in tuner. If the set that you prefer has one, fine. If not, get a set top box, preferrably from the same manufacturer if they make a decent one, so you can use a single remote to control the monitor and the STB.
When I lived in Florida, I had a Samsung DLP and a Samsung STB. I still have the monitor but I sold the STB to somebody that wanted it on the AVS forum.
I guess one of the drawbacks of the STB is that you need an extra connector on the back of the monitor. My Samsung DLP only has a single DVI input, so I used a DVI switch. Yeah, that was a PITA, so just make sure you're monitor has enough digital inputs.
