I need a cheap phone plan that I can't find!?

I need a really cheap phone plan so i can at least text more then a few times a month. I got a stupid tracphone, but the minutes are never enough to even hold a conversation. So i was thinking about straight talk. 30 dollars a month for 1000 talk and text sounds pretty cool. But, I saw something on a commercial about something about 20 dollars. And I'm like wha? So I googled. Nothing came up. Does anyone know anything cheap that i could possibly afford? It'd really help though :)
