Is Sharp even in the running.

[pier4r]

For the little that I know the sharp advanced scientific calculators (from 2000 on, I have a 2004 model still using it today, el-506w) are pretty good. Without picking more beefy calculators (I mean a larger package), I couldn't find any competitor that is strictly better.

The new models should be on par with the top casio 991 series.
