to be honest it would be better and cheaper to build your'e own, all you need is a heat mat , a wire shelf, a poly box, a thermostat and a digital thermometer, we bought purpose made incubators when we first started but found the home made ones worked the best and maintained a better constant temperature, i'm sure there will be a thread on here on how to make one try doing a search.
camzoo is good for cheap thermostats and heatmats. the best digital thermometer i got off ebay and the wire shelf is a cake cooling rack and the poly box came from from a aquaruim pet shop, alot cheaper than £80 that most decent sized incubators will cost
