I have also enjoyed the upgraded program. When I modify solver lines, I often need to store several "versions" of solver lines in the memory and I wish if I could save the older line and copy it to a new line to modify it (I mean it is often painful to re-enter a whole long line again). Do you think it is possible on 17BII? In case I need a serious debugging, I prefer to do so on the solver in 200LX where I can copy and paste the line.

Yes, this might be a major drawback of 17BII, although I rarely need the trig functions. Previously, I had been using 19BII, and it has trig functions. In addition, the separate alpha-keys are convenient to enter equations. However, 19BII is too large and heavy for my lab-coat pocket, and it was painful (and dangerous) to change the batteries of 19BII.
I have 27S and this is also a very nice calculator with the same Pioneer form and the handsome solver with a lot of mathematical and financial functions. The problem is that it does't accept RPN input. Probably, "27SII" with an RPN option might be my ideal calculator.
