I just picked it up from warehouse here in Queensland, Australia that makes them. It's one of the standard sizes they make.
The tank plus styrofoam (for Warranty - $15 Extra) was AU$294, which is pretty cheap, you could expect to pay around $450-500 for that size usually.
Edit: May as well add this while the thread is bumped.
Have decided against getting the 3 Geophagus sp. "Rio Pindare", I've got the pair of Keyholes in there now and I feel it would overstock the footprint long term. I might possibly add a single Acaricthys heckelii but I doubt I will, as I would rather have a shoal of Geophagus than have them seperate. Plants are still the way they are, but I've done a minor rescape after one of my Keyholes managed to get themselves stuck in a chasm. It's the same general layout just with some rocks swapped around and such.
Still contemplating adding the Corydoras, and possible a shoal of 12 or 18 high bodied Tetra, possibly Bleeding Heart. Trying to find out whether they'll get large enough to avoid the doom of my Blue Acara.
