Bingo. I recently declined to buy a 16c revival in miniature form because it had membrane buttons that were reported to be flaky (sure wish I'd bought one when they were generally available, not exactly cheap on eBay: http://www.ebay.com/bhp/hp-16c-calculator http://www.ebay.com/bhp/hp-16c-calculator).
I'm still using the 28S I bought back in the late '80s (also bought a spare recently), it does what I need, displays four levels of the stack, and between the quality buttons and discipline in double checking the stack before doing operations I never made a calculation error in my problem sets. Any keying error were due to hitting the wrong key, not the keys themselves.
- aidenn0 11y agoI use a 35s, which replaced my 11c. It's available for around $50 new and is better than the 11c in every way except battery life (I think I had to change my batteries about once a decade with the 11, it was ridiculous). Unfortunately it only shows 2 levels of stack, not 4 like the 28s.
- hga 11y agoWell, the 2 extra lines come from the 28s being a graphing calculator, they're essentially free. They're nice, but having gone from 1 line in an 67 to 4 in the 28s, I'm pretty sure the important threshold is "more than 1 line". On the other hand, I wouldn't want to switch to a 35s because I read it has a stack of only 4 levels. I find it very useful for summing a long list of numbers to key them all in, and then double check against the list as I do each addition. Hmmm, it's also easier to keep track of where you are in that process with an extra 2 visible lines.
- aidenn0 11y agooh, I didn't know the 28s had more than 4 registers; that's nice. I have no idea why they didn't do this in the 35s.
