	Or, if you read the instructions, try 37oC . . . 

	If you're really paranoid, order BRL's (EXPENSIVE) library or 
(even more expensive) maximum efficiency competent E coli.  Other 
companies e.g. Invitrogen also sell competent bugs (just to show I have 
no affiliation with anyone).  -And go with the manufacturer's directions 
for each variety.

	Otherwise I agree completely with Martin here.
