Currently using a Sony 40" which I got for free, before that a 37" LG, also free. There's plenty of people who for some reason want to get rid of their "old" television to get one of those newfangled "smart" things, have a look around the local classified ads/Craigslist/Freecycle/and you're sure to find plenty of options. As long as it has HDMI and a big enough screen you're set.
