I am thinking of buying one...one incubator retailer over here raves about them and states they are flying out the door as they are so fantastic. The other says the rcom 20 were rubbish so they never even considered supplying the 50s when they came on the market. So before I spend my money- I would like to hear from anyone who has used one - especially for ducks eggs- as thats what I will be using it for. How good / bad was it. Would you recomend them???
