It is the HP 38E/C.

Granted, you see the HP 31E, 32E, 33E/33C, and 34C on ebay. You also sometimes see the HP 37E (although IMO this is pretty rare), but check me out if you wish, but it seems the 38E/C shows up MUCH more often.

My question is: Why do you think that is ? I have some thoughts, but I'd like to see if anyone here has an opinion.

Since the HP-38E/C is my favorite, I'll offer an opinion.

The 38E/C was HP's first handheld financial to really get it right. As remarkable as the HP-80 was in 1973, it was so limited in resources, that it left a lot to be desired. The two Woodstock financials had some new features, but there wasn't a major upgrade until the HP-92 printing model arrived with full TVM5 capability. The 38 offered that plus programmability. There must have been a huge number of them sold. The legendary HP-12C is almost identical in function, except for a few additional functions and the horizontal format. I suspect a lot of users who were happy with their 38's ran out and bought the 12C because of its style and the fact that it fits so easily in a shirt pocket. When you think about it, the HP-38 functionality has continued for decades in the form of the HP-12C, mostly unchanged.

As for me, I prefer the vertical style of the 38 and maybe I'm just old fashioned, but I prefer the LED.
