Ebay and another forum I am not sure if I can say here has a much larger fuji community and hence gear for sale. I have been posting a lot there.
I paid $450 for my 14, $515 for 23, and $203 for fisheye all on fleabay, so there are solid values if you are patient.
I was editing pics yesterday from Fe, 14, and 18-55 and I must say as someone who has owned cheaper canon glass and L glass, the fuji lenses in addition to rendering well are very sharp (and samyang is also known to be super sharp center, and it really is). Fuji renders highlights and clipping a little weird sometimes, and the waxy faces at higher ISO i have seen some evidence of, but when I was considering it someone said consider getting fuji lenses the same as L lenses, and that is really true enough.
