i agree 100 % on the redwood bator's here is mine... not sure who made it but its the best incubator I've ever had... made around 1950ish with GQF electronics in the early 2000nds...

Chris,
I had a good year hatching Reds. Didn't keep data but well above 90%.
Rather than going the GQF route look for one of the old redwood incubators. Leahy made some good ones.They're thick walled [& heavy]. I think they hold heat & humidity better thanthe GQF. I had a Sportsman but got rid of it as the old Leahys worked better for me. I have 2 of tem & the most expensive one was $65.
