Root Rooting, Easy to remove?

[Burky]

I am thinking of rooting my new Motorola Defy but am wondering if I have to ever send it back to Vodafone for repairs how easy is it to remove 'Root' is it as easy as the iPhone equivalent by 'Factory settings through iTunes' but via the device?

rooting modifies /System so factory resetting will not help you
most rooting apps should have unroot option

Even that will do I just wanted to know how easy it was to remove it if needed, any one recommend a good root app. I have been looking at z4root any good?

Basically, the steps to unroot are, flash an unroot zip through recovery, then run a stock ruu to flash everything back to stock.
