What accounting software do you use?

I used to use Quicken in the 90's (and loved it) and then a few years ago I switched over to MS Money and am not that enthusiastic about it.

I'm looking for something online that can run my personal accounts as well as those for a small business.

I've just been looking at but that seems a bit too basic but is in the right sort of area. I have no problem with fee based services as well as the free ones.

Does anybody have any suggestions or opinions about online (or off-line) accounting software? What are your experiences?
