[Blindmath] Accessible calculator

[Matthew_2010]

Hi all,

I'm hoping someone on this list might know of a good small accessible 
calculator one can buy somewhere. A model number in order to track it down 
on my own will be greatly appreciated. I'm looking for a handheld unit I can 
carry in my pocket. It need not be very complex as I'm only looking for a 
basic calculator and not a scientific calculator or anything that advanced.

Thanks,

Matthew
