How do you like the HP 34C?

I'm probably not the best qualified to comment on HP-41 durability, but, for what it's worth: I used the 41 as my everyday calculators from 1979 until about 1989. I bought an HP-41C in the first week you could buy them, and replaced it with a 41CX about five years later. In 10 years of using these calculators, I never had any trouble with them. The cases were sturdy, the keyboards were crisp and reliable, and I never experienced any kind of failure whatsoever.

Regarding the HP-67, I never owned one back when they were the top of the line, but I got one on eBay a few years ago. It appears to have been used heavily, but treated gently. The yellow and blue markings on the faceplate have not rubbed off, but the f, h, CLx, and R/S keys feel a bit mushy compared to rest of the rest of the keyboard. All the keys work fine, you don't have to push hard on any of them nor do any of them bounce. And the case feels solid as a rock, it doesn't flex or creak at all. If it weren't for the fact that calculators have become so much more capable in the 40 years since my 67 was built, I could see myself using this unit as my daily calculator even today.
