Need more info on everything except Greg [I've bought all my feeders from him and price/service has always been great-he was even gracious when one check got lost in the mail {no, really, it did!}]:

1] What kind of fish are you feeding? How big are they?

2] How large is your pond?

3] How close do you live to your pond? How often will you be able to check/refill the feeder[s]?

4] What size/type of food do you plan on feeding?

5] How far do you need the feeder to throw food?
