--- Thanks for the reply.
Yes i could do the "sums" myself. I guess in retrospect i should have 
asked if anyone had a favorite board for the 2000 series that might 
meet my wants.
 One of the problems with using light is it's speed. A detector 
should work something like: pulse a laser, wait on laser to return to 
detector, divide the time required between pulse and detection by 
speed of light, look-up time as feet or inches, display on lcd to 
make user friendly.
 All these processing cycles happen more quickly than a 
typical "hobby" micro can process. If i were better at coding i could 
probably figure out how to ignore the first few "returns" after 
sending several pings of light, giving the micro more time to react 
and averaging the return in time to display on a lcd.
