Where to get DUAL rotary encoders in US?

[bosskong]

Hello, does anyone know where to get dual rotary encoders?  I think that's what they're called at least.  I'm looking for two knobs in one basically - for example, so I could turn the bottom part of the shaft to change the crossover frequency and turn the top half to change the amount of boost/cut.  I'd also like to have a jog and shuttle on the same shaft.  

Something like the ones at this site - http://www.flightdecksolutions.com/ACC/rotaryencoders.htm but I want a bunch of them, so I definitely can't afford $85/each... :o

Any info would be much appreciated... Thanks

Just a thought for a possible cheaper solution, we could use the encoders with inbuilt pushbutton switches and tell MIOS to change parameters according to the button state... Push encoder in, Change boost/cut, dont push in, change frequency...

Someone else was talking about this before in another thread...
