both myself and dez have 150 gal tanks. it was seeing his that convinced me to go with that size, the height is really nice to work with. we both have single corner overflows, i'm not sure about his but i have only one hole, a 2". return will come up the back and over the top. the overflow is smoked glass. i am personally not a fan of centre overflows, to me they take up too much space.
some people advocate not using any braces and instead going with thicker glass all around, but i went with euro-bracing. it's not intrusive at all imo.
the tank was made by inter-american in calgary and cost me $550, and that includes a starphire front (not sure if the sides are starphire or not, i'm waiting for canadian man to tell me when he sees the tank)

. i picked it up myself, not sure how much shipping to your location would be.
