I know you, like me, only want the tank, but
Innovative Marine is doing half off their custom systems, and they are based out of California, and may be able to offer you better shipping terms. I don't know, but maybe if you contact them and ask, they may be willing to sell you just the tank.
My last thought, and I hope you don't think I'm calling you "poor", I absolutely am not. But have you thought about grabbing a standard, Aqueon 90 gallon just for now, just to keep your tank going? A 75 (same footprint and stand size as the 90, but WAY cheaper) or a 90 gallon standard would be just a few hundred dollars tops, it would keep your tank going, and then allow you more time to consider other options, or save up some more for a different tank. If you then got a nicer tank, you could absolutely sell that Aqueon 70 or 90 locally, so you wouldn't be stuck with it.
I've been keeping fish tanks a very long time, but I am, admittedly, a budget reefer, not that I'm comparing myself to you. I've had larger sized standard tanks in the past - a 180, a 125, a 90, several 75's, etc. And I've had now 5 smaller, contemporary rimless tanks with the low-iron glass, and slick silicon seals ranging from 10-40 gallons. This was the first time I every really seriously researched a larger tank that was rimless, low-iron, with nice seams.
Admittedly, I was sticker shocked to say the least. But, after having my head spin around a few times, I made a plan, and put money towards this purchase, and now I feel like I'm ready.
Again, I hope that helps and best of luck with whatever you decide!
