What brand Plastic Conical are you running Amandak? Ive read bad things about certain brands and wondering how its working for you.
As for Conicals, i plan on making a fermentation chamber much like a walk in cooler. it will be controlled by a Coolbot attached to a Window AC unit for cooling and a Heater.
Still not a cheap option:)
It's an Ace Rotomold or something like that. I picked one up after several recommendations from other club members. After spending months comparing SS concials, I figured that I could replace the plastic conical 8-10 times before I made it to the cost of a SS conical. Most other people that have this set up use a plastic dump valve and siphoning source, but I went with SS fittings there because it seems like the area of greatest weakness for harboring buggies.
I also toyed with the idea of a walk in cooler (with window AC and Coolbot) but decided it wasn't right for me. Too expensive, too much space and not enough individual control over each fermenter.
