It is sometimes difficult to justify single-use appliances, and not just due to the cost. The space that the appliance takes up, whether in a cupboard or on a counter, is space that cannot be used for other multi-function appliances, as a prep area, or for anything else you may want to do in the kitchen. Products that make an effort to be compact, or at least efficient with the space they take up, always have an advantage over those that do not (all else being equal).
That said, quite a few users say that this waffle maker isn't as sturdily built as previous versions of the same model, and that if you don't get the top heating plate aligned just right, it can fall off -- an injury hazard if the plate is hot. The top of the G48TD also gets very hot. Some use pliers to bend the metal clips that hold the heating plates in place, which helps them line up better -- or you can just use an oven mitt to protect your hands.
