New Aquarium Advice

I am buying a new 150 gallon tank. Considering Marineland with corner boxes, but worried about them leaking - the reviews on their own site have lots of terrible reviews about leakage. Found an alternative - the "lifetime" tanks by customaquarium.com. They have great video showing how they make their tanks, and cost is actually less. Only drawback is their standard tank has a top-mounted center overflow, so holes are at top and you have to run the hoses down the back. Any advice would be appreciated.
