I have a series 1 38mm aluminum and an original 38mm SS with modern buckle (Best Buy deal). I love being able to use both on one phone instead of switching bands. I prefer the weight of the series 1, but love the look of the SS with leather band. I originally ordered a series 2 38mm SS and returned it because the additional weight and depth, even though minimal, made it heavy and awkward on my small wrist. I'm very happy with the combo I have now and together the cost of both was less than the series 2 SS watch with modern buckle.
