Home Depot has all the parts. I built mine with 1.5" PVC pipe reduced down to 4 different $3 brass sweeper nozzles(less than $30). I guess it would really depend on the following:
1) GPM delivered to the pond at what PSI(really pump capabilities).
2) Do you want the pump to run continuously while filling the pond? I feel it is better than to have the pump turn off and on repeatedly. Does the well supply other needs? Will you have a pressure tank on the system?
