Working with the EN I see a lot of the machines. We have been buying since the 300 PIIs and are still buying now that we have the new model 733s. These are serious business machines, on the whole easy to work with, although the drive carriage presses on the cabling and connectors on the old case, although this has been rectified.
Very reliable. I cant think of one that has had a major problem and weve had 100s pass through us with no faults and the older machines still run fine (I am writing on one.
I would say that they are a bit expensive for wha tthey are, so I would not reccomend for homw use, go for the EP. But for office use, to have as a company workhorse I would thoroughly reccomend them.
