If you're looking for a full-featured commercial application with statement downloads, etc., I would suggest Quicken. Quicken 2006 will convert Money 2005 and earlier. If you are using Money 2006, you'll have to wait for Quicken 2007. Historically, Quicken seems to be released every August.
I use Budget from Snowmint. It's a bit of a different concept, so it depends what you're looking for. It's great for keeping a budget, not so great for tracking your investments.
