I bought an LG still air and auto egg turner and I like it. I only tried hatching once and never got a chick....but that was my fault. I never had problems with the temp spiking. BUT the only problem I did have with it was keeping the humidity high enough. I had every water well filled, washcloths, sponges and extra water bowls and still couldn't get it high enough. Plus the water wells are hard to tell where they are to re-fill if you got a turner in there, since everythings white. This time, I drew a line around each water well so I can see where to add water. I've had mine plugged in for 2 days now and its holding the same temp so far, no fluctuation. Eventually I plan to get a better one, but as for right now...this one was cheap (about $80-$90 for bator and turner). Also the knob on the LG is very touchy. You barely have to touch it to change temp.
