Should i flexirent my slr or 30 month intrest free?

I'm getting a nikon d5000 but i'm not sure wether i should flexi rent it or go on 30 months intrest free.
Flexi rent allows you to upgrade and to have full insurance. But i don't know if i want to commit to it as you have to make a payment everymonth and it seems to be abit of a hastle.
I just don't know if i should just do 30 months so i can pay for it sooner.
Any help would be great.

This is a nice camera and if you know how to use it, go buy it outright and pay it off as soon as possible. When you rent a camera it is not yours to keep and you will have to give it back at the end of the lease term or pay for its market value at that time.
