I just got my 35g from watertanks.com. It was $88 shipped and took about 4 days. They told me 3-4 weeks so I am happy. I know that the threads for the top is not a bolted down piece like a lot of the others so all you have to do is buy a pipe flange gasket and get a rubber stopper for the blow off tube. It is not a full drain, but it only leaves a few ounces in there. Also, it is not a 61 degree, it is 45.
