There are no other equivalents to those models unless there is a non-solar model with the same functionality that I'm not aware of. Well, the 2nd editions are equivalent to the first editions apart from cosmetics and some updates to the CODATA constants.

Quote:Also, what Casio model is the next step up from the 115ES Plus 2nd & Canadian 991ES Plus?

That would be the 991EX and non-solar 570EX (and their international variants), although some features from the 115ES Plus and 991ES Plus C are missing from the 991EX/570EX.
