How to recover lost images from a corrupted flash card?

OK, it's a total nightmare. I lost all images because of low batteries (I think). A buddy told me that he heard that there is software that can recover images from flash memory cards even if they were reformatted. I've Googled "image recovery software" and "recover photos" and narrowed it down to two titles
ImageRecall 3
and
Recover My Photos
The first one seems to have very favorable reviews. The second one does the same but is ten bucks cheaper. Any first hand experiences with these two? Or should I try something else?

LukaBuka,

Do a search in these forums you will find there is plenty of info about this already.

Hint: Start in the Help Forum for info on this.

I just looked but couldn't find anything. In the Help forum, I just started this thread there on what to do.
