I personally don't like second hand electronics. Mostly because I don't trust people and they are hard to inspect / test where as mechanical devices are very easy to inspect and test. However, you can save hundreds if not thousands by buying used.
As for size it depends on two things.
1) how far away you plan on sitting from the TV (use this for a rough guide - http://www.homeappliancegallery.com/images/articles/720p-1080p-viewing-distance-tv-size-chart.jpg )
2) how much money you want to spend.
For brands, I don't know what you have in South Africa but you could always list some brands and see what people have to say.
