Bournes makes very nice optical encoders, although they are a little pricey. 
Clarostat also has a pretty nice encoder that's a little more approachable.

There are a number of good mechanical encoders out there.  Panasonic has 
some pretty decent low resolution encoders that start under a buck.  Bournes 
has some 9mm encoders but they are very low resolution. Still, if you need a 
volume control in a tight spot ...

Relatively recently CTS came out with a non-detented mechanical encoder with 
relatively high resolution as mechanical encoders go.  It could be a 
challenger to an optical in some price-sensitive applications.
