I got mine from Strombergs, they don't have some of the options that yours do but have quite a few more breeds to choose from.
I made a 4' x 4' melamine box and going to get a thermometer tomorrow to find out if I'll need a heat source but will probably go with a highly recommended "brood plate heater" like this should I decide I might need one:
I hear they are much less of a fire danger and the lamps are notorious at falling into the box and starting fires and my chicks are going to be in my woodworking shop although it sounds like a pretty good way to a broom handle through the hole to prevent that.
Amazon delivered the "No-drown waterer" bottoms today that will fit my jars. Looks like yours only screws onto a quart size jar thread.
