[Nfb-science] Basic 4-function calculator with speech or large print suggestions sought

[Patrick J]

Group,

        I am looking for a basic (addition, subtraction, division, and multiplication) calculator with either speech output or large font (16 point or larger).  It has to be portable and relatively inexpensive, and preferably carried by a chain store such as OfficeMax or Best Buy, ordering online isn't a problem, just that I'd like to try it before buying it.

Thanks for any and all suggestions.

Patrick.
