I just bought a similar model from
Brinsea. I have not yet used it, but it is EXTREMELY sturdy and well built. Very sturdy plastic and the unit is actually heavier than I expected for an incubator, especially since I am used to the many different styrofoam models on the market.
If you order the Octagon 20 ECO with an autoturn cradle, it will be about $150 for the total package direct from
Brinsea. That is the same price range as the styrofoam Genesis 1588 with autoturner. With the
Brinsea, of course, you give up some hatching/incubating space (it is designed to hold only 20-24 chicken eggs as opposed to the 40-50 eggs that the Genesis can hold), but you do gain a nice, sturdy unit with a full 2 year guarantee. Both the Octagon 20 and the Genesis 1588 are very popular models here on BYC.
Because of my irregular work and school schedule, I needed to order the autoturn cradle with my unit, but I have read plenty of BYC posts which state that it is no big deal to rotate the unit by hand a few times a day. Yes, you do rotate the whole unit rather than the individual eggs. For some people, this is an advantage because you do not need to open the incubator to turn the eggs.
You could always order the Octagon 20 ECO without the autoturner to see how it goes turning the unit manually and then maybe purchase the autoturn cradle at a later date when/if you need it or when you can budget it in.
