If you don't mind spending money, Corel's AfterShot Pro (formerly Bibble) is a great piece of easy-to-use software. I find it as easy to use as Darktable (which is my favourite F/OSS raw tool), but also somewhat prefer it's rendering.
There are a few other reasons that I use ASP as well. There are several good/useful plugins available, and the big one: Adjustment layers.
Darktable is coming along nicely, and they have some VERY intelligent contributors. Lots of good help on freenode's #darktable IRC channel too.
Edit:
It's also worth noting that you can try ASP for 30 days, so you don't have to commit just to try it. Also, look around for deals, I don't think I would have purchased ASP at the MSRP, but I got mine for under 50 bucks, which I think is reasonable.
