Check to make sure the 2400 has a light lid and holders that will do 4x5.  I
think the 2400's light lid is smaller than the 2450/3200 light lid.  From
the tests I have read, you gain somewhere in the range of 10% better
resolution with the 3200 over the 2450.  I am assuming the 2400 uses the
same optical system as the 2450, but that is just a guess.  With the 3200,
you also get improved negative holders.
