Query: Poor compared to other Sharps

We have a variety of Sharp calculators in our office. This model was by far the slowest and loudest, and despite being the most recently purchased unit, it was the first to break. The description on this page calls it "high speed", but at only 2.0 lines per second, it pales in comparison to the 3.5 lines per second of Sharp's EL-2196BL. On top of that, I think the lps rating is done with simple keystrokes. This unit was very slow to print special lines (memory functions, # key entries, etc.) compared to our other models.
