The example I gave was purposely oversimplified to make it easy to 
explain and understand. In reality the records will be far more complex 
and the numbers perhaps in the hundreds of thousands.

But still I do agree with you. I was just trying to see if one of the 
three choices was clearly brain dead or clearly the best one. Would 
using a hash repeat over and over the text of the keys (I assume 'no') 
or have far slower access? Would using a class that never would have a 
method incur a major performance overhead because accessing each value 
required a method call anyway?
