So I have been browsing around Sparkfun, Adafruit, Digi-key and my usual shops online but can't figure out exactly what to ask for to get the part I need, or where I could buy it. I'm assuming it would cost less than $1 and be easy to find if I knew the name.
I was initially going to use buttons to scroll up and down through a menu, but I would rather use a single wheel on the side that I slid up to move up through the menu and down to move down. I am hoping for something breadboardable, but if not I can always make a breakout I guess.
In essence I guess I'm looking for a scroll wheel, but prefer something much smaller than a mouse scroll wheel as the device I am designing is going to be the size of a watch. Any ideas are appreciated!
spark fun has a blackberry roller ball
but it is $16 :O
Probably too big, but look at

http://ecb.omron.com.sg/application/mobile.htm might supply a sample?
http://www.ec21.com/offer_detail/Sell_momentary_smd_jog_lever--13086846.html could be useful if you can find a distributer.
Search terms may be 'jog wheel' and also do a picture search that can help.
Maybe this side "navigation switch":
Also available on a breakout:
Interested to see what you end up using!
