I find myself in the same situation that you are in and I have tried both Norton Ghost and another program called Powerquest Drive Image. Both programs are quite exellent and the resulting images can in most cases be compressed enough to fit onto a cd or two; unless your hdd is really big. They are however not exactly what I'd call inexpensive and I'm still out there looking for the really cheap option.
I do tech-support for a public school and they have quite a few machenes and are not all that well-funded, so I need a very cheap option.
If anyone out there can help me with this I'd be really gratefull.
