I've never owned a
Brinsea, and they may be the best for small numbers of eggs, but very pricey for what you get. I have several models of Hovabators and LG's, and most are a lot of trouble as mentioned, but one model is fantastic. For about the same money as a
Brinsea Mini Advance (7 egg capacity, cheapest model with auto turning - $
159.99 on
Amazon) you can buy a Hovabator Genesis with an auto-turner from Cutler Supply (

168.85 + shipping). This model holds 42 chicken eggs in it's turner and is also "set and forget" (until lockdown). It's all digital and has a much better heating element than the other styrofoam models. I dry hatch, so I put the turner and eggs in, plug it in and mark the calendar. Within an hour it will be at the target temp and stay that way - highly recommended for anyone that doesn't want to pay
Brinsea prices. Most people want more than a 7 egg capacity, and the
Brinsea they really want is the model that holds 20 eggs, that one is $357.65, more than twice the price of the Genesis (and it holds only half as many eggs).
For about the same price as a top of the line
Brinsea that holds 40 eggs, you could get a used Sportsman cabinet incubator that holds 288 and will hatch at least as well as any
Brinsea. I have a Sportsman I paid $450 for and I love it. I also have an old-style Hovabator for a hatcher (I set and hatch weekly). The Genesis is what I loan out to families for the experience with their kids. It is as simple to operate as the Sportsman, but more portable and "observable".
