If you're set on the curved bow front kind of tank, then go ahead and buy it.
However, if you don't mind that much, my advice is to not buy it and wait for a standard 6x2x2 - 180G.
These secondhand should be significantly cheaper than 700CAN (you may be able to get tank and cabinet new for that). They will house any large cichlid, don't have the extra annoying height to make maintenance/gravel vaccing a PITA, and there are so many accessories that go better with standard sized aquariums. The main thing is that it is 24" wide throughout, so that large fish can use the full length and turn around, rather than swim to the end in a continuously narrowing corridor then be forced to turn around in a cramped dead end. They will also have significantly larger footprint = better gas exchange at water surface so better oxygenation, and also slightly more territory for cichlids to claim. Extra height above and beyond 24" in a cichlid tank is not that useful whereas extra width most certainly is.
