My mom introduced me to American Scientific and Surplus and it is AWESOME! They have a great catalog and a great website. I just found a gadget that you hook up to the tv and it won't turn on unless the person has a special coin (they give you the coins). You set certain times of day when it will accept the coins and then each coin gets 30 min of tv time. I know it won't handle every difficult child, but some of our difficult children might not be able to hack it. Just thought some of us might find it handy, esp at just $10. Take a look around the site - too cool!!! My mom gave me a little book with a ton of post-its in it. Big ones on one side, medication and then 5 rows of flag sized postits on the other and that is where she got them.
