are you looking for a local dealer/builder or one of the types academy or bass pro sells? I would call academys and ask if they still have any left over from there clearance sells, you may find one that away or post an "I want" on the classifieds
It is hard to beat a magnum feeder. To be honest with you I am an outfitter and hunt deer for a living and I LOVE their photocell feeder. It is the most depedable feeder unit I have ever owned and it will sling corn. Be careful walking to your bowstand if you get there late. Will get an eye put out.
The best feeder I have experienced is On-Time. No digital anything, sealed great for the weather. To set times all you need to do is place a clip on the rotating time disc. Runs on 11 double A batteries. Awesome rig and I have had them for years. If one were to break, mail it in and they will fix it for you for the cost of shipping.
Thanks guys, feeder is bought--Magnum 55 gal w/rechargeable 12v battery, solar panel, digital timer, great lid clamp---on sale at Magnum Industries--$30 bucks off! Getting a strong built 14 foot tripod soon.
