Hi Buffy,
Commiserations to a fellow R-com sufferer! Incubators just shouldn't do this to eggs, should they?
I think a fully automatic model is too much to ask for less than £100, if you want anything better than the Suro.
We originally bought the Suro, having asked my parents for an incubator for Christmas. They bought us a
propagator instead
, but were then so embarrassed by the mistake that they insisted on buying us an incubator as well - that's why we went for a cheap one!
When it went kaputt, we replaced it with a Brinsea Octagon, and would definitely recommend. You can get an "Octagon 20 Advance" for about £150 by shopping around. That gives you temperature control (duh!), and a humidity readout, but no pump or cradle. However, the design of the octagon means you can do the turning yourself very easily, just by rocking the whole unit from edge to edge whenever you walk past it - you don't have to open the lid and turn the eggs or anything.
From experience, it seems you get what you pay for I'm afraid!
