Need help deciding on a new tank

[nyshoots]

I'm finally in the position to upgrade to a bigger tank. I'm considering the following Elos concept 80, Innovative Marine SR 60 the new cadlights shallow reef or getting a Deep Blue 57 rimless and piecing it together. Any thoughts

I was thinking of a DB 57 rimless but have heard lots of people say not to go that route because of the size and position of the overflow. They make the tank without the overflow if you want to go about drilling it on your own. Just giving you some info I came across in my research.
