In that link, she built it that way for a 55, which is about 5 inches shorter, front to back, than a 75. It's basically a modular template that you can take and refine to fit your tank needs. I like the = sign layout because it'll support the long sides entirely, while the plywood will distribute the weight pretty well. Then again, when looking at stands, I tend to over think and over engineer, I think.
Another thing you can consider is that there are some heavy duty shelving units out there that'll hold 1000 pounds per shelf. A 75 is typically in the neighborhood of 900 pounds full. It won't be as pretty as an actual tank stand, but will fall between the cinder block stand and an actual designed tank stand in pricing.
