I deal with HP calculators since 1982, but I got into contact with them in 1978, when I saw and played with an HP21. I had a few models in the beguining of this century (2000) but I could afford buyin used models and new ones in 2001; now I just dare dreamming of them.
I own many RPN models: 25, 31, 55, 41C/CV/CX, 42S, 11C, 12C, 15C, 16C, and the RPL ones: 28S, 48SX/G/G+, 49G. The financials 17BII and 19BII were bought for learning and teaching and, perhaps, writing a book. Too late: no more available as new ones, no one will print a book about an equipment that cannot be bought as new. Oh, yes, I also have some HP41 stuff and an HP82240B IR printer.
Hard to select a "Holy Grail" in this team. IF, and only IF I have to select a stand-alone for science in general, I'd go for the HP48G+ mostly because I can buy another if it's lost or stollen. Any other will be hard to replace. If the HP15C is a choice, I'd go for it instead the HP41. The HP41 needs enhancements, say, plug-in devices to be a powerfull piece. If you add an Advantage ROM to the HP41 then you'll have all Voyagers at once (does Advantage have financial functions too? I don't know). If you add an HPIL to the HP41 you'll allow it to talk to the world.
If my Holly Grail is based on the HP41, I'd add an Advantage ROM and that's all. But it will be far from one resource: LCD graphics.
And I am almost sure an HP41 with an Advantage ROM is a lot more expensive than a fresh new HP48G+. And let's face it, guys: I don't care walking with an HP48G+ in my pocket, but I'd be dam scared and cautious if I have an HP41CV/CX with an Advantage ROM im my pocket... Wouldn't you?
