Although I workout in a gym around 4 times a week, I have a doorway chinning bar for home. The kinda thing advertised on those informercial channels (I'm seeing a pattern, there ;-)). The one I saw advertised was called the Iron Gym, but the one I bought was from ebay, a Medicarn / P90X one.

It has loads of hand positions, from very wide grip, to close grip / underhand, to neutral grip.

Very stable, too. If you're really tall, though, maybe a doorway one wouldn't work too well.
