Have been reading that alot of forum users love the
Brinsea Eco version. On sale for 99.00 plus shipping. You order if directly from company. Would be great for your banty eggs and is almost fool proof.
I personally like the Browers Tophatch. My oldest one is over 10 years old and finally bit the dust. The crank shaft gave out on the turner but the incubator can still be rotated by hand. I even have a back up one to use as a brooder as soon as they hatch out. It keeps the eggs cleaner and no mess in the bottom to contaminate the other eggs hatching out.
I like the fact that you can mix turkey, goose, duck and all sizes of chicken eggs in the Browers and still get a good hatch.
They are cheapest from Strombergs at around 158.00 and that includes shipping.
