If I had good insurance I wouldn't worry about it, especially after Mikaila31's story. I do keep good homeowner's insurance incase of it - and/or anything else. It just makes sense. However, I've never had a tank fail in over 38 years. I've had some pretty scary looking used ones over the years too. Boweing glass, cracked plastic rims, damaged and moldy-looking silicone seams, chiped edges on the glass - you name it. They all held up.
Crooked and/or wabbly stands are usually what causes tanks to fail; even new ones. As long as the stand is perfectly flat and not "crooked" - ie higher on one corner or "twisted" - therefore putting a "twist" on the tank, you are probably ok. You should put any new or used tank on it's stand and before filling it, inspect the four corners where tank meets stand and stand meets floor. If everything is the same and nothing feels wobbly before you fill it, it will be ok with water. A wabbly stand that gets sturdy after the tank is filled is a dead give-a-way for potential problems later. If the legs feel uneven on the floor you should level it and stabilize it with something first. I have used everything from paper to plywood to plexiglass for this (wedge it under the high spots between leg and floor). A slightly tilted tank - say, the water is slightly deeper across the front than back but is the same depth from side to side - is usually ok, as long as it isn't "twisted". "twisted" is what you can't have.
I know a fellow who had 2 brand new 90 gallon tanks burst inside of a month before he realized the stand was crooked and causing it. Good level stand = no worries.
