glad you posted the link... I hadn't seen the new ones yet.
I love my old Brinsea octagon 40. I love the fact that you can rock the entire machine back and forth to turn eggs, and I like the egg trays. With the egg trays I can pack in a bunch more eggs than it says you can. And I can pack in whatever I want (chicken, duck, bantam, quail, all in the same thing and whatever way fits best)...use toilet paper to cushion between eggs as needed.
The new model you are stuck with little thin egg holders. No way could I stuff in a jillion extra eggs.... and no easy egg turning if the Turner busts.
