Desolate One said:They both have great ratings on VersionTracker, I've been checking them out since I'm also in the market for one. CCC is much cheaper @ $5 vs SD @ $20. Unfortunately I haven't used either yet so i can't give you my take on one or the either. I'm sure someone will chime in that's used these products though.
