A picture was also supplied but it did not post here. It shows the unit with the auto timer referenced in #1 above. I inquired about the following: prices of all units, group discount, sunset/sunrise controlability, warranty, shipping costs etc. I am awaiting a response. This may or may not be the same manufacturer as yours but why don't we wait to hear the response before an order is placed. Maybe a better offer or product is available. Just my 2 cents.
