This is a really neat item. I love automation as much as the next guy but there is no way anyone should pay $1000.00 for this. Make it cheap enough ($250.00) and a lot more people will buy it and you will recoup expenses and still make a tidy little profit. If not I will just have to spend 3 minutes a day to keep checking it with my trusty $50.00 Hanna checker and $6.00 regent refills.
