You should prowl ebay and find yourself an HP42S! With the economic downturn, prices are generally lower than I've seen in several years, unless the HP42S is new in the box!
The HP42S 21 years after introduction is stunning. I thought that 12 years ago when I got my first one, and I still think that today.
As for color scheme...it's like about everything else that HP produced after 1986. It's disadvantageous, ugly, and sucks big time. It's chosen only for left-coast artsy BS appeal. For the Pioneers, it's suck-butt orange on fecal brown! What could HP management been doped up on to come up with that? I'd love a HP42S++ that also had the capability of its worthy financial cousin, the HP17Bii, and the color scheme of the HP-15C. Almost perfection!
Perfection would also require that the ENTER key be placed above the /, *, -, + keys, the way it was for pre-Saturn calculators. Putting those keys on the right and leaving the ENTER on the left for the Saturn era was absolute incompetent idiocy by HP! Apparently, the visual appeal of a keyboard with less effectivve key arrangement won.
I'd like a mini-SD card too, but I doubt that the power demands of such a device could long be met by a calculator powerd by a 357 or 2032 battery.
