[Leica] Leicaflex or Leica M ?

["Tony Salce" <NadinaTony@bigpond.com>]

Could list members proffer a view as to the merits of using an SLR like the
Leicaflex as opposed to a Leica M.

I presently use a Leica IIIa and an  Olympus OM1and am considering the
purchase of either a Leicaflex SL or an M3. Having held a Leicaflex SL in my
hands, it is absolutely no comparison to the Olympus. Similarly the feel of
say an M3 is lovely. However I really don't know whether to stick with SLR's
or to launch into rangefinders.
My photography is centered upon family and travel.

Are a Leicaflex and an M compatible if one was to get both ?

Your thoughts would be appreciated.

Kind Regards,
