I use iBank (http://www.iggsoftware.com/ibank/index.html). iBank 2 is coming soon which looks amazing, but don't use the beta right now because it stopped working after the last 10.4.3 update. I'm patiently using the original iBank until iBank2 gets out of beta. There's another app that looked pretty good too, but I forgot what it was called. I'm sure someone will post it.
