I've seen people's photos run with Rad Lab and frankly, I can do most of this in Lightroom 2 (I'm too mean to upgrade to the current version!). I process all my photos through LR anyway, so, as Nana says, I run FREE presets across everything, playing withe which one works best for that photo - although I have a few go to presets. I haven't bought a single preset, not one. Maybe it's just me, but $99 sounds like rather a lot of money to spend on something that isn't a major piece of software/hardware.
Go on, give LR a try - with Adobe's 30 day trial, you won't go back after trying!
