Now I don't know what deals are available in US, but in UK; if you buy Elements and register it with Adobe, Adobe may e-mail you after a few days/weeks and offer CS5 at half price, which is a good deal for most. That gets you the better ACR than Elements (although it is probably still a match for iPhoto) and of course, proper 16 bit editing, cloning, layers and fully functional masks.
Cheapest starter, if it works on a Mac (someone to confirm this would be nice), is Elements.
Cheers,
