Crumbdad...i cant find the exact price list at the moment but for one 3000x1200x800 high was about $400.
The smallest they do is 1930x700x400 slimline style and a heap of variations in between including round ones as well

The cheapest was well under $200. I think we were looking at one 2300x700x800 high and it was just over $200 (I think! babybrain is a bit foggy!)
