Hello again, I believe I have created solid cheap safe breeder. (I'm going to use it fo sho)

It is faster but more expensive. Copper platings can always be replaced with regular ones. (amount of heating cells will go down as well, obviously)
Cheaper version: http://www.talonfiremage.pwp.b…d7asky7nvwm9qng8cj1wf1rkj
Cheaper version gives almost the same results as the listed one, but uses one more plating (more heat !) and as a result of that, can handle extra heating cell. (faster !) It also costs considerably less copper, which is somewhat important. (at least to me)
