I don't currently have one but did pass one through.
While the basic filter is very good will all the standard Eheim features, I would not personally want the electronics involved with the E'3. Unless there is some real driving need for some of those features, I like simple machines as they tend to have less breakdown.
I do now use a 2075 which is much the same filter but without the electronics and it is my favorite filter, being a step up from the classics. Things I like are the baskets, the pad at the top which can be cleaned without doing a whole filter clean and the cutoff system is much improved.
