I agree, the CM-100 is the one to have. I've used mine daily for ~15 
years & it still works great. Amongst the many nice features is its 
ability to show the status of Carry and Overflow bits based on 
selectable word sizes of 4,8,16, or 32 bits. 

The only more capable unit I know of is the HP-16, but at $200-$500 
on eBay, they're becoming collectors items. Besides, I own an HP-16 , 
but still use my CM-100 most of the time.

The CM-100's seem to go for $30-$60 on eBay.

Here's another nice CM-100 pic with some of its specs:

It's not really suitable for programmers. It doesn't do shifts and logical 
operations, for instance.

So does the nth Lab RPN calculator I use on my Palm Zire 31.
