I normally don't like paying for software, but like Bob I'm a bit doubtful of my own ability (but also patience and laziness plays a factor for me), my AFMA routine so far has been "these shots are all front-focussed! lets change the AFMA by 1 point and keep shooting".

If the software can be downloaded and installed without needing a registration key though, I'd be willing to lend myself to Linux-installation-testing under Wine (as long as it supports XP, the newest DPP that is Vista&7-only doesn't work on my Wine...)
