They're fine - I had two F3's and then later on, two F5's that I used in the same way I use D3's now: as work-horses, along with a couple of M6's and an FM2 body as back-up. I sold some and kept the mintiest-ones for myself.
Since going digital in 2001, I used to take the Leica 'away' with me, but since the D2x was issued to 'us' in 2005 I haven't bothered with that either.
It grieves me that these are effectively reduced to shelf-ornaments now, especially the Leica...
I've occasionally thought of selling them, but the near-mint F5 is only worth about £200 at most, so I'll just hang on to them til I retire. Maybe I'll get back into film-use when I don't actually have to work at this any more...
Oh, and I forgot about my F2-AS which is at my Dad's - though having just been superceded by my old D1x body...lol
