I never was a fan of the 2350, as I agree with the user unfriendly. This instrument encourages department straitification with worker bees gathering data and geeks disseminating it to reportable format. This could be advantageous for mega sites where you have a seperate shift for instrumentation, but precludes people from being aware of the big picture on consise sites.
That said, Ludlum doesn't update superfluously, so I would think this 3000 would be a beneficial update to the 2350.
