We wanted a device, rather than PC software, for balancing financial statements. I didn't want a paper-tape device; so I checked Amazon and found a great 12-digit calculator that records up to 160 entries and one can review/correct figures; even after a list has been created and calculated. It's a good-size unit, measuring about 5.5" W x 7.75" L, and it has a large display. The Compucessory CCS02200 calculator sells for just under $12. I think it's a good find and am passing it to GH.
