Value of HP28C vs 28S?
Just getting back into building the collection of HP's RPN Graphers. I remember some saying last time I should look into a 28 series as they were HP's first real graphing calc in the series.

I've been watching E Bay and Amazon for a week now, and have observed that the S usually sells for multiples of the C. Is the only difference the RAM? Is there something else that's really different about the S version? Seems they go for about the price of a 48GX most of the time, so I've really got to think about the value there... Smile

Thanks for any pointers to a 28 series newbie!
