Backup Software - Opinions Wanted

[RGD.]

I have decided that the backup software packaged with Win 7 just plain sucks. On two different boxes it simply locks up and refuses to work. Tired of it so am looking at these two softwares:

O&O DiskImage 5 Professional Edition

and

Acronis® True Image Home 2010


Any users who have opinions, pros, cons, etc etc would be greatly appreciated.

Thanks

Ron
