I have been looking for ages for a reasonably priced Gray encoder incorporating a momentary switch. They are surprisingly hard to find. Maplin and Rapid don't carry any kind of Gray encoder much less cheap ones. Finally I found these: http://cgi.ebay.co.uk/12mm-Rotary-Encoder-Switch-With-Keyswitch-10pcs_W0QQitemZ350126007559QQihZ022QQcategoryZ67003QQrdZ1QQcmdZViewItemQQ_trksidZp1713.m153.l1262
In case the link buggers up they are an ebay shop called sureelectronics. At $1.60 a piece these are great value for money especially since this price includes the knob which can often double the cost of a pot.
These are the same component as are used by Big Clive on his splendid knob RGB LED controller: http://bigclive.com/knob.htm
Sometimes sureelectronics also sell a fancier looking encoder with a silver, narrow knob. These also have a momentary push switch built in.
Obviously at this price they aren't bulletproof Omron quality but for project work or even daily light use these are a cool and elegant way to input positive/negative values to your code.
If you haven't used a Gray encoder before there are a bunch of code examples all over this site of using them as both interrupt generators or just polling them. As an input device for controlling things like volume or intensity and mode (with the momentary switch) they are the dog's danglies.
