Well let's just start our own price comparison.  Here is a quick start.  Add to this list and add detail about what the different apps can and can't do and fix any of my errors.  I think we should focus on comercial use of the apps, because some things are free for home use, but not business use.  This would be a great thing to have on one of the websites.
