I like saving a buck as much as anyone, but from what I have seen with incubators, you get what you pay for. At styrofoam prices, I would buy the best styrofoam I could afford. The ebay plastic incubators are attempting to look like an RCOM or Brinsea, but there is a reason they are 1/4 of the price. If your budget is $115, I would buy a Hovabator and talk to a few of the many members on here who know how to use them. If you want a digital, plastic set and forget, then you need to spend a little more money. From the reviews I have read, I would have more faith in a styrofoam incubator than a chinese plastic
