I've always liked the DS18B20 for one-off projects, but I'm also looking 
to move to something with a reliable source.  (Mouser actually lists 
these as "Obsolete.")

One key feature for me is that the TO-92 form factor makes it easy to 
throw a 2- or 3-wire cable on it and use it directly as a remote probe. 
  The other is that you don't have to calibrate it per-unit or per-batch 
(unlike thermistors, yes? haven't used them myself).

The new Microchip MCP970x family has both these features (though it's 
not as accurate in the TO-92 package).  I've got a few samples coming; 
has anyone else tried them yet?

And, are there any other alternatives that come to mind?
