svnx for macs? i use eclipse with the subclipse plugin plus tkdiff. i haven't had trouble using svn command-line...git, though, constantly behaves unexpectedly and requires vigilant reading of the manual. i've reverted projects back to svn just for the sanity (also, as a team project, i don't want other people wasting time on version control, especially when they require user friendly interfaces, which is lacking in git. tig is cool, but not user friendly enough for certain team members).
btw, mercurial is a pretty sweet alternative. i've already been seduced by github, tho.... i wish they could be repohub instead....
