Well I've read all 490 posts on this thread, and am convinced that the Incuview is the incubator I want to get. I had settled on a Brinsea octagon 20 ECO, but they raised the price on Amazon from 249.00 to 289.00 So I started looking for something that was more cost effective, and believe this is the one. I'm impressed with the reports of customer service, and the in depth study that so many of you have posted thank you all for the great pics and posts. I'm thinking a wire cage from fan to floor during lockdown/ hatch time would possibly be a solution (probably overkill) for the circulation and limb thing, but will have to think that one through for a while.
