As to the refresher Courses I bought the CEC CD for 2006 for 325.00 after S&H. I am constantly referring and searching the rules for what may apply to any particular job. I see this year the CD is 325.00 plus S&H . I actually use the CD more than the Code Book as i can print off a page or 2 if needed. Now I see the new Code book is 150.00 it really wasnt that long ago when the CEC ran about 30.00. I guess i should quadruple my rates seeing how CSA can.
