As for the Glasscages quality, the tank is fine...but not a masterpiece. Arrived a little later than promised but was correct as far as the design we came up with. No major issues, no leaks or chips or anything. The silicone was sloppy on the front panel and needed some trimming. You'd think they'd get at least that one side of the tank right, eh? They charged for black silicone and yet inexplicably used the clear on the lower bracing which was just a disappointment more than anything. Their customer service is "crochety". As long as you aren't looking for corporate flowery talk and lots of "yessirs" and niceties, it fine. But I can understand why folks get turned off, their CS can definitely be interpreted as rude. I'd say its a C+ job....passing but not special. Until you factor in the price that is. When you figure that a similar design tank from anyone else is going to run you 2-3x as much, then it makes sense if you are trying to reef on the (relatively) cheap.
