In the next week i'm going to buy the core with end tanks already on it. It seems to be the best value i've found so far but i'm trying to get the price down further but cant do that without more numbers.
They are costing $750 + $28 postage from QLD. Price will be better if i can get some more people to buy at the same time as me.
They are Bar & Plate and 600x300x76
