I bought a 65 eleven years ago and absolutely love it. One year ago I bought a 67 to see what it was like. I was very disappointed. The card reader would not consistently work. I returned it twice to the Ebay seller and he could never quite fix it so it would work consistently. He finally refunded my money, after a bit of haggling.

While the 67 certainly has more programming features than the 65, I was really put off by the labeling of the keys. I could never quite remember if a label went with the key above it or below it. That was a serious distraction that was never a problem with my 65. I also did not especially like the color of the 67; a kind of sickly green.

I eventually bought a second 65 in case my 11-year-old one ever fails. Both 65's run like troopers and I especially like the simple RPN programming model and reduced programming instruction set. It is amazing what can be accomplished with 9 registers and 100 lines.

So my advice is: buy a second 65.

Interesting point of view. Thanks!
