I'm not liking that they change Maxi-Jets!!!! I needed to order up two replacement Maxi-Jet 1200's and saw that they have changed these pumps. I don't like what I'm reading as far as the reviews. This is deja vu Koralia all over again. Am I being paranoid about ordering these new MJ's.....or is there some other similar small pump that has proven performance. Please help.
