I got mine at wal-mart- in, out but not at the same time for 9.00.
I also have a couple of the 4 in ones: Time, In, Out and Humidity
The great thing about these is that they have a memory and tell you at what time the Hi's and low are. I just move it from enclosure to enclosure... about 30.00

Before you criticize someone, you should walk a mile in their shoes.
That way, when you criticize them you're a mile away and you have their shoes.
