What flower pots have good drainage for cactus?

I have found that you don't need a special pot for cactus. I have sand in to bottom of my pots and then I mix sand with the soil. You want the soil you put them in to be as close to a desert as possible the will grow very well. I don't water mine that often either, they seem to prefer being neglected. I have even put catus in buckets and they do very well.
