Just go to wal-mart and pick up the cheapest thing they have. I bought one of those when I moved out. I paid $25 for it, turned off region restrictions and it lasted me four years (and longer since I got rid of it with upgrades). With a 20 inch tv, a dvd player is a dvd player. Also, after the four years and it surviving a house fire, I sold it on ebay for $50.
That is my advice anyway.
