I brought my TV from the US in 2011. I use a Freeview box which works just fine. (Mine was dual voltage, so no need for a converter.) The picture via the Freeview box is actually better than I got with a digital antenna. I connect via the HDMI connection.
The TV is a bog-standard Vizio, and was not expensive, and as we had a 40' container there was no cost to ship over and above everything else that was coming over, plus I have the advantage of watching all my DVDs via an ancient dual voltage multi-region DVD player that has both NTSC and PAL output.
