They are not cheap, by any means, but they are supposed to last forever. I have buddies who have had theirs for 25+ years, with no problems, still keep the same shape and form. I paid $160 for mine, not exactly sure what that comes out to in pounds, but I think it's a very worthwhile investment. However if the EP3's work for what you need them too, then no need to change! I went over to customs because I felt the need to.
