ExactAudioCopy ripping software

Hi - I'm little confused

Who can recommend which of ExactAudioCopy programs to buy, in order to rip my 1500 CD collection.(bought a Sonos system with a 500 gig HD)
I want to extract the maximum information.

Been to their website, but they have too many products to choose from - please advise.

Plus once I have selected the right one - are their any recommendations regarding the process you might adise?

Thanks
