Does anyone have both types of Incubators that run off of 110 and 220? I was wondering if anyone had done any research on the cost of them to run. I only have the GQF's but have found 2 of the larger ones that run off 220. I am concerened about the cost to run the larger type of bators. Mainly how efficient they are. I have been happy with my GQF's but need more room.
