I just got done reading Aquascapes pond builders bible, and they swear up and down on their products, however my sprinkler supplier sells Savio products, and carries them in stock (only local supplier tha carries pond stuff that i know of). So the savio would be much more convenient, and would have some staff to help back up the products. What do you guys use, what are the pros and cons?? I am just getting into the pond aspect of landscaping and would like to pick a brand and stick with it. We have two pondless waterfalls to do this spring. Kind of like the Savio pondless setup better i think, other than you would have to move some gravel to access the pump (not a big deal) What do you guys think??
