what one the LG or the sunnyside up ?the incubator works great for me!!!! Easy to control.
if it dosnt have a thermostate the sunnyside up one would have to be watch extreamly closely probly woudnt be worth it to be honest , if you can aford to do a incubator with a fan so like one of the brinesea , a hovabator with forced air or a LG with forced air, if you want a small bator vs just a cheap one there is this one
