What I think
Fair price, given the depth (well, width) of the tank and the fancy stand and top. I looked at this for awhile and decided that I didn't want the huge top, so I wasn't going to pay for it.
I suppose the real question is, if you're looking at a tank of that size, is it because your fish need a bigger tank . . . and, if so, do you actually need an even bigger tank?
