I got mine at wal-mart. cause as fas as it goes for me, u just need green fabric. Well, you can buy a professional one if you want it and you can afford it. But to me, good lightning and a green background always work.http://www.youtube.com/daltonrenaldo
Watch: Flying board test, Chroma Test and Giant Rody. You can also watch magic boy. But I used my green screen for a different cause.
