So..I don't post much but I enjoy lurking on the forum. I recently purchased a pristine financial calculator on eBay that I can use which will allow me to use my 41CX exclusively at home as I am afraid to lose it on the road for whatever reason. Well I purchased an HP-17B...which doesn't use RPN :).
It is in absolutely perfect condition and even came with the original box, manual, sleeve..everything. I will keep it and give it to my son or maybe a coworker I care about..I don't know yet.
I just thought I would share my mistake as I have made worse and this just makes me laugh.
