I think you would enjoy building one for yourself. There are plans on here to build that are quite nice. It is basically a box as nice or as crude as you wish, a 225 watt heater element a fan of some kind and a thermostat. All of this for around 50 bucks depending on what you want to do for the wood. The turner is the hard part. You can fashion some sort of device that is semi manual or you can buy one that fits the hovaboator for about 50 bucks.
A deluxe turner motor and timer can be nearly150 dollars and you still need to build the racks for it.
In any case on made of wood especially if you find a handsome box of some kind has a lot more eye appeal than any of the styrofoam incubators.
I built mine and enjoy knowing I built it. I like looking at it since It was my hand work. I am not woodworker, but can piddle a bit.
The styrofoam incubators work very well there is no doubt, but i have a thing about the stuff. I dont like eating off it, I dont like drinking coffee out of it and every time the lid squeaks I get the willies like fingers on a chalkboard. LOL
Please not being critical of the stryofoam incubators just offering my view.
