If you are going the logten route, just a heads up, as of right now you need to upgrade to OSX Lion. I wasn't too happy with that so I posted on their support forum and they let me know that they will have 5.8.2 for Snow Leopard on the app store soon. It will also be eligible for the free upgrade to 6.0. I have been hesitant on upgrading to Lion due to the bad reviews and the fact that some applications are still not working properly on Lion at the moment.
