For about $5 more, look at this one: http://cutlersupply.com/zen_new51/index.php?main_page=product_info&cPath=2_24_28&products_id=193
I highly recommend Cutler Supply, I've ordered from them twice now and been happy with their service.
I think the electronic thermostat is worth the extra, though Sally swears by the old-time wafer ones. If you want to save even more, the still-air version of the one you found goes for about $55 on Cutler's site. If you know any computer junkies, see if you can get them to hook you up with a fan from an old computer and a power supply from an old cell phone or other DC voltage electronics. I replaced the worn out fan in my old Hoverbator with a PC fan and it works great. I use it as a hatcher and turn the fan off (unplug the separate power supply) once they start to hatch to prevent shrink wrapping.
