I chose the Brinsea Mini Advance because 1) Idiot-proof 2) Only wanted to hatch 7 eggs 3) My autistic son could watch them hatch. Wayfair.com is cheapest in my search at $157.39 and free ship, also 10% off your first purchase. Amazon was $163.98 w/ free shipping; Brinsea.com was $159.99 and shipping is pretty high.
