[volt-nuts] HP3457

[Marvin E. Gozum]

The 3457a is younger, has added functions, such as amps, and better 
long term accuracy; the 3456a is just a DVM.

The previously posted link has a large comparative database:

3457a tends to be have more unobtanium, compared to the 3456a.  For 
700 euros for a calibrated 3457a, its better to look at new 6.5 digit 
DMMs such as the 34410a which I see farnell lists for 850 euros.

or the cheaper 34401a or equivalents from other makers, Fluke, Keithley etc..

again, electronicsandbooks has a wonderful comparative listing.
