People say good stuff about it but you have to consider that you will need windows XP for it and the license system appears to be a little bit too depending on the windows registry and hardware that you use.
With that in mind just be aware that you might be asked to clone your system when you install SeDiv full version, because even small changes to the windows registry appear to cause the software to request for a valid license.
Did you try WDMarvel ? You can try it for only $9 USD - One month of use and if you like it you can buy the full version for $100 USD. Might be cheaper then SeDiv and it's under constant update as well.
Or you might consider investing in a multi-model tool like the MRTLabs offer.
