The set I like most, is the one by Murray Perahia.  I do not like the
period instruments,, the sound is often as if played from the inside of
Tin cans, and the players often add a lot af notes and embellishments,
which are defenitely not Mozartesque, but that is of course a question of
taste, If you really want period instruments, try Van Immerzeel
