for my size, i chose the vfr 400. small, handles... perfect. not big, not tiny.
i am almost too small for a 600, but I can still handle it. just make sure you don't ride outside your limits...
also... the vfr 800 (or is it 750...? I can't remember) has vtec... I was on the back of one and it's quite an interesting feeling.... that bike was WAY too big for me.... but it's not a hard bike to ride.
