Zach - it doesn't take an advanced engineering degree to know that each "box" is not equal as you claimed. A tub that is about 1mm thick plastic is going to have very different thermal and insulative properties then a AP cage that is around 12.5 mm thick of PVC. That is not rocket science. One size does not fit all and to claim it does is foolish.

Heat tape is cheaper then RHP's no doubt, but not as efficient and does not provide the same control over gradient.

But with statements like "a box is a box" I doubt we are going to get anywhere, no matter how long we go back and fourth. So lets just agree to disagree.
