Going with a Red Sea AIO tank with or without Sump in cabinet?

[katcon]

I am getting ready to purchase a new Red Sea Max E-260 AIO tank and was curious on the thoughts of getting it upgraded when I buy it with the sump in the cabinet or not? Thoughts? Is the volume (69g) of the aquarium big enough to see the benefits of a sump? Would it be easier/cheaper to do it later? Thanks for all the feedback.

To upgrade sump or not?

Isn't the whole point of the Max to not need a sump? I'd go with the REEFER series if you want a sump.
