You can get them forced or still, with or without automatic egg turners. There are several types. Look on ebay, there are dozens of listings there for Hova Bators alone.
I prefer the Hovabators with the fan kit- you can buy them separately or buy them together in a kit (usually combined with an automatic turner also). GQF's website has a number of options for Hovabator incubators. I have 2 Hovabators- one with 2 small viewing windows (ordered the fan kit later), and one full view top (came with fan kit-got smarter the second time!). Good luck!
