I just purchased a RooR Little Sista Ice-Master 3.2 (http://www.everyonedoesit.com/online...ProductID=1577), and the reason I got a beaker is because it looks like the water filtering on the straights isn't nearly as good (the Zumo 4.2 doesn't allow for very much water filtration). Do the straights really hit that much better? $135 is very inexpensive for a RooR, but I want to get as much out of my money as possible.
