I'm a firm believe that if you want to root then you need to do it yourself! Admittedly, the Droidmod process will do the work for you. Additionally, I prefer SPRecovery over Rom Manager/ClockWork. SPRecovery has always preformed as stated. I can not sam the same for RM/CW
My sense is that if you take the time to learn the processes then do the root yourself then when you have a problem you will be able to figure out the solutions for restoring your phone.
My two cents.
