I used an HP-41CV for years until it broke. I did buy a 28 at some point after that and I just didn't care for it. I was looking at the SwissMicro HP-42 clone the other week. I could really be tempted by that or this one. But, honestly, I have a couple of the landscape HP calculators and those are more than enough for anything I do and I have a 41CX app on my iPhone.
