go for zxr250 if there is one. zxr looks alot better than zzr.
zxr has a tacho meter that goes 21000 rpm. thats insane.
i guess in north america bikes are just for fun.
in asia we need to ride it everyday under hot sun.
zxr performed pretty well. my friend ride that bike (zxr) everyday and i never see him need any major repairs.
here is a pic of zxr
