I just googled and priced one. Wow. I can't see that much money for so few eggs being set.
I use a styrofoam hova bator with picture window and fan. New that is $110 (mine was new in box old stock for $85), Little Giant auto turner to put in it on sale from Tractor Supply for $40 and a cigar box hygrometer for $15. I got the picture window incubator for the kids so was more money but for $140 I get 100% hatch rates when using my own eggs.
Oh and forgot to mention I can sit 41 eggs at a time. If you want a top notch incubator people around this site are gaga for the Brinsea Octagon 20 but that's the same price range as the Turn-x your looking at. Think it holds more eggs though.
