I actually came in at $177.64 (some of the below prices have changed since I originally compiled this list) It took a little bit of searching to find the absolute best prices. Your results may differ especially if you can buy local and avoid the shipping. Here's what and where I got all the parts: SmartHome.com Motor $83.92 http://www.smarthome.com/31427/Add-A-Motor-D20-Chicken-Coop-Motor/p.aspx Solar Charger $22.94 http://www.smarthome.com/68033/Sunforce-Products-50013-Solar-Powered-12V-Sports-Charger/p.aspx Battery $12.96 http://www.smarthome.com/44395/Univ...0-12V-7Ah-AGM-Sealed-Lead-Acid-Battery/p.aspx Sub Total $119.83 Shipping $9.79 Total $129.61 Cabelas.com Digital Timer $44.99 (plus tax on local pick-up) http://www.cabelas.com/product/Amer...-Feeder-Timer-Only-Units/915295.uts?WTz_l=CQO Grand Total $174.61 Avoid DiscountHomeAutomation.com http://www.discounthomeautomation.com/Solar-Panel-Battery-Timer-Kit-AAHSBTK I originally ordered a complete set up from them and over 30 days later the only thing they had done was charge my card on the day of the order. Customer service was non-existent. Finally had to call my bank and cancel the charge. Hope this helps, Alan.
