57 is too big. I wouldn't go bigger than a 55 at your height, unless you have very long legs and very long torso (= very small head, haha)
the wabi has some very road bike ish geometry, which is alright if that's your thing - it depends whether you tell people you ride "track" bikes or "fixed gears"
personally i like track bikes, though this page is another testament to the quality of wabis
if i were you, i'd save up and buy whatever bike you want (fuji track, felt t1, trek, cinelli, etc quality aluminum shiot)
then get a longer stem and move your seat back on the rails on your kilo and use it as a junker/ bar bike
because if you just got another budget steel frame you might want to upgrade again in a year or so
