Getting my incubator soon. Just trying to figure out if the advanced incubators are worth the extra money. Couldn't I buy a good temp/humidity and use that with the economy version? Also what size to get? 24 or 48. It seems like the 48 egg version did not get as many good reviews, so it makes me worried. What incubator do you have? Are you happy with it or do you wish you would have gotten another model?
