Some people have asked me about the cost of putting together this type of incubator. These are some pretty rough numbers but should be close

Mini fridge $0-$150 depending on used or new

Heat tape with cord and connectors $10
Flourescent light with inline switch $10
Aluminum tape $5
Cleaner $2
Plexiglass $5 each
Egg box $5 each
Lid $5 each
Perlite $8
Egg grate $10

Thermostat $60-$140 depending on the brand

So for as little as $135 you can have an incubator that works great!

The end result is priceless
