Thanks for the huge response to my hex calculator request for information.

The results are :

HP 16C, programmable, $70 approx. : four people say its great (if you 
				don't mind paying the price.)

Casio CS-100, solar powered, $15-20 at Best : six people reported that 
				it does the job and you can't beat the price. 
				Lots of people here are using this one.

Casio fx-451 : Favoured by one, its the only one that has all the 
				scientific functions as well.

TI-36, solar powered : Owned and liked by one person, borrowed by many.

Texas Programmer : Hated by many, liked by no-one, the keys bounce.
