I just bought a Brinsea Oct 20 Eco and the cradle turner....I bought it direct from their site and it REALLY wasn't much more at all than the MINI. I LOVE IT! I just hatched out 9 eggs in it and let me tell you they used up ALOT of room in it...so glad I didn't go with the mini. I would say even trying to hatch more than 12 chicks would be REALLY SQUISHED in the OCT20. Absolutely buy the cradle! It's awesome...once you get it...you'll quickly realize how much work it does!!! I LOVE that it doesn't roll the eggs but rather just tilts them. I LOVED that the temp was preset. I bought a little cheap digital hygrometer from ebay...CHEAP...works awesome! I did have to adjust the temp a few times...but it was really simple and no spikes at all very steady....I just turned it 1/4 of the way and that would increase or decrease the temp by exactly 1 degree! Amazing! I did have to scotch tape the vent holes at the end b/c one stays open and the other only closes most of the way. The tape did the trick and got the humidity up! Once they started hatching the humidity goes up naturally. Then I just used a medicine dropper to add water through the vent hole as needed...easy! I LOVE mine! I would NOT go with the smaller "MINI" version now that I've got the bigger one. BUT...I just want to say that there is a thread on her about the INCUBATOR...on ebay...seems like a GREAT little machine..holds more eggs than the mini...comes with a turner...DIGITAL settings ...and it CHEAP!
