I used to have Ghost 2003, which I am sure you already know is quite slow and works in PC DOS. It always worked well and restored my system when necessary.
I updated to Ghost 10, which is a lot faster to use and not so complicated. After using it a couple of times it started failing to validate the back ups I had made. I queried it with Symantec and their reply was something like - don't worry if you can't validate the back ups they are probably ok!
I wasn't happy with Ghost 10 and Symantec gave me a refund. When I re-installed Ghost 2003 I could not get it to work properly at all and ended up using Acronis True Image 9, which actually is a lot better than Ghost 10 'promised' to be.
My advice is to stick with Ghost 2003 if you're happy with it. If not I would seriously consider Acronis before forking out on Ghost 10.
