I think the Sharp EL-W516XB (and similar models) and also the TI-36 Pro are in the same general category.

There is a good comparison between the SHARP EL-W516 and the CASIO fx-115ES calculators at:

More than a simple comparison, the two volumes presented here (175 pages) are also a good tutorial on how to use these models with a lot of examples. The information is usable for newer Casio and Sharp scientific calculator models as well.
