Hi, Just wanted to say that i built one of those fish tank and aquarium heater incubators 4 days ago ready for my cremsicle's eggs. Having never built one before i was slightly scepticle but it works really well and mantains temps between 80 - 82 degrees at all times.
If you need a cheap, easy to build and very effective incubator id have a go at putting one of these together.
