Several months ago there was a thread regarding the Aurora fn1000. I bought one and have been carrying it every day in my shirt pocket. The thing I like about it is it is very thin and has a protective case....just right to carry in a shirt pocket or pants. The keys are mushy, really mushy. Quality is pretty good....it is manu in China. One strange thing about it is it appears it was designed by a lefty. Opens just the opposite of the HP 19B. As for the financial functions I only use it for un-even cash flows and loan calculations. And it does a good job. It is very slow. The documentation that comes with it isn't great, but you can stagger around and find the answer to most questions.
For someone who just has to have a financial calc at hand and demands RPN, this is not a bad bet at about $31 including freight. I was skeptical at first, but after 6 weeks of carrying, I really would miss it.
