I don't know of any that are shareware/freeware that come even close to matching the features of Money.
Like southerndoc mentioned, iBank is one of the bigger ones. Also check out MoneyWell.
Personally, I use (and rather like, even though I think I'm the only Mac user that does 😱) Quicken Essentials. It connects and automatically updates all of my checking, saving, and credit cards accounts and can do some simple reports, which is all I ever used Microsoft Money for.
