I recently bought a KS-1 and am extremely pleased. It is wonderfullly constructed and very resonant and "alive." The neck and string spacing are wide, but having gotten used to it (took only a few sessions), it is very comfortable and welcome. The neck is amazingly smooth and clean to the touch, it is the best part about the instrument. I was worried about the "plain Jane" looks and squared-off fretboard (vs. something carved and more ornate), but in person it is really well proportioned and looks great, with a really well-done satin finish. I read about folks having issues with Kiwaya's choice of friction tuners on the Eco Series, but I am getting on just fine with them, they hold great and are easy to work. I can see now why some folks swear by friction tuners - tweaks vs. turns to get in tune - yes, it is easy to go *sharp* but overall quicker tuning vs. 14:1 gears. The handles are also large enough to provide decent leverage (vs. a Flea's tiny handles that are not so kind when hands are tired). I thought I was going to be relegating myself to concerts, but this uke has shown me what's possible in sopranos (vs. the more readily available kind that for mew always proved hard to play) and I am having a great time with it.
