The $549 one from Amazon is the one I have and is totally set and forget. Hands off.
The other link you posted is for the Eco version. No humidity control, no digital read out, no turning cradle, no cool down option. You would need to manually turn it but you can buy the turning cradle seperate.
Most hands off is the Amazon one
