I'm getting together a 48x24x24.  I paid only $250 for the glass, silicone, drilled holes, the tank adapter thingies (for the plumbing), and the overflow glass.  Mind you, he gave me cost as a favour to my mom's work, but without the discount I would have paid only $300 for the whole kit and kaboodle.
I'm getting a steel stand from Imperial Aquariums here for $175, epoxy painted.  Not a bad price for everything, I think.  Didn't wanna DIY the stand because we don't have much for power tools, and I don't want a ton of water on the basement floor
