That's where I got my thermometer lol. I went to a computer repair shop down the street & asked if they had any used computer fans for sale, they gave it to me for free! The only thing I had to pay for was the water heater thermostat and the thermometer. I think when I get some extra income I'll get a few extra thermometers and a wafer assembly.
I am hating my wafer thermostat right now. It will be doing fine then all of a sudden it will go really high. I have to adjust it down then spend two days getting it back where I want it. Then after 3 or 4 days it goes wonky again! Grrr! I am afraid it is going o cook my eggs if I am not monitoring it every few hours.
I think when this batch is done I am going to sell my new incubator and buy some silkies to brood my eggs.
