yup, i broke down and did it. It's just AWESOME!!!!! i set it for 7:30AM, and can sleep in on the weekends for the first time in 2 years! I set it for 5:30PM and can stay at work (darn it.....) knowing that they are safe and sound inside their warm tajmahal. It was so easy to install on my existing up/down sliding door. I was kinda scared that it would crush them in an accident, or etc. It's perfect. I bought the less expensive version from http://www.discounthomeautomation.com/Add-A-Motor-Chicken-Coop-Motor-AD20 The kit was perfect. had everything included. I went out and purchased some 80 pound test fishing line for the door, because the kit didnt have enough line, but other than that its great! total came to about $180.00. I felt really guilty about spending the money, but the girls pitched in with their $100 of egg money i have saved up, and my cat pitched in another $20, and my moms cat happend to thow in another $20. Then my neighbor lady pitched in and $10 because she loves my MayMay and wants her to be safe. so, really it became affordable. Seriously, it is a great kit. I purchased the solar panel and battery with it, that's what made it a little more expensive for me. so i reccomend you all "go forth and automate!"
