I'd recommend building one.. even if it's just big enough for one egg turner. .
Buy a egg turner. .46.00
Buy a temp controller 16.00
Buy a fan 14.00
Buy light sockets 20.00..
All you need is a box then.. cooler or type...
I know that seems crazy..
I've got 3 incubators. .little giant, hova bator, farm inovater. . And they work for awhile. .then you end up throwing away the components maybe keeping fan... and buying the above items anyway.. rebuilding them..
Just my 2 cents... not knocking anybody.. just they make them so cheap.. and most only incubate once in awhile. . So they they just don't make them to last..
I would say out of those 3 hovabator is the best insulated. .
Stay away from the cheap little giant 9300 still air.. it's only 50.00 I know. .but you get what you pay for..
I've never had the expensive brinsea. .
