I think when you get to a certain size of tank acrylic begins to be the more affordable option. I also think it's the safest if done by the right person and still I won't go down that road due to scratching. I don't even REALLY care if I scratch a glass tank here and there it does happen. With acrylic unless you are far more careful than I want to be several times a week it is many many scratches which look far worse than a few in glass.

Even though the steps in building a tank may seem simple and I consider myself handy I'd never build a large tank myself. Depending on size I also think it's totally worth having it built on-site and in place. I'm sure it's all in my head but I think moving even a new tank must stress the seams a little bit? I think an 8x4 tank fits into this category but it'll certainly cost you more to have them come build at your place.
