[Yaaarc] Analog Mux recommendations

[Keith Mc. (Route-To YAR)]

I am looking at a robot application that needs way more 0-5V 
analog inputs than the MPU provides.

Anyone have experience/recommendations for an easy to use analog 
mux chips (preferrably available from Digikey), that EITHER:

a) Runs from single ended +5 and will go near the rails without problems
b) Includes charge pump circuits (possibly with external caps, etc.)
c) Is cheap, easy to find, and easy to apply, but needs +/- voltages
   easily generated from either +5V or +12V.

I need to mux two sets of 8 analog signals onto 8 analog input lines.
I'd prefer a pair of quad 2:1 mux chips. (IS there a "16:8" chip? 
That'd be GREAT...)  I guess I *could* use (4) 4066's, but I'd need 
to invert the select signal for half of them, which adds parts.

I'm also trying to avoid a PCB design, as this is a "2 of" only,
and I need it quickly.  I plan to solder breadboard it.  The signals
are very low freq sensors with decent drive, so I'm not too worried
about noise.

Part recommendations, anyone?
