Red Sea max 250 or custom 60 - 70 gal ??

[RSM2008]

I have had several reef tanks over the years but set up a RSM 130 in the office. Now I want something larger. Should I wait for the new RSM 250 or build a custom system from scratch? What I like in the RSM is the integrated base & canopy (its in the office) lighting timer, built in skimmer and relative low price for all-in. Looking for 60 -90 gal and sps capable. Any pros or cons?
