Exactly what I was thinking. I suppose Freud would call it "calculator envy".

I find it interesting what people have in their collections. I'd really like to know what HP-Collection has in his. I know he has a few Curtas, which are missing from this list.

Another approach in deciding which calculators are common/popular/interesting is to consider which calculators have had recent after-market options designed. Or, How to Have Even More Fun With Your Favorite Calculator.

HP-41
* Clonix and NoV modules by Diego Diaz
* 41CL CPU board by Systemyde
* 3D-printed parts by Nate Martin and others
* DM-41 by SwissMicros

HP-42S
* DM42 by SwissMicros

HP-48
* FRAM memory modules

HP-71B
* FRAM71 memory module by Hans Brueggemann

Speaking of the 71B, I was disappointed to see the 71B supporters not chime in, and I know who you are! Between three of us I know we have 29 x 71B's.
