I love my Brinsea ECO 20, but I just hatch small scale (now anyway). However, you can build your own cabinet incubator. Check this link:That's how I felt About the brinsea too, they seem great but I want the option of more. Not that I'm a continuous hatchet nor plan to be but just like the option of being able to put in more eggs. I have the hovabator genesis 1588 and even though the digital reading isn't great I still feel it held its temp and humidity well, aslong as you don't open the lid. I definitely agree if you hatch a lot and frequent then something better and more expensive will be worth it! It sort of saves money if the eggs you purchase have a better chance at hatching so worth it to sink money into a cabinet bator.
Good luck finding a better and bigger bator!![]()

Otherwise check out places like Craigslist. Here there are 2 Brinsea 380's for like $400 each. Quite a savings from retail.
