I've been looking into this too with my digital camera just 3 weeks away now.

iMatch seems promising and to have all the features and more that I was looking for at the right price, 49.95. Heres the link for you if you want to check it out. iMatch

Cumulus looks promising as well but not sure if I like the look of it as well. But downloaded the demo for it as well to see which I like better. It runs at 69 I believe. Cumulus

Presently I use ACdsee and I knew it would leave me wanting for more.
Hope this helps. Doug :)
