My second GSXF, which I bought from a member of the facebook UK GSXF owners group for next to nothing. It was originally in a pretty rough condition, but with a little work and some parts, made me a pretty song (200% over purchase price, minus a few quid here and there for parts, a lot of which I already had) when I sold it on.
More details on this bike are in the Restore/Refurbish section.
