I APPRECIATE WHAT YOU ARE SAYING, ITS GREAT VALUE FOR A LARGER CO THAT HAS SEVERAL WHO WILL USE IT, ONE COURSE AT FRANKS WORKSHOP WILL COST £400 - £500 INC TRAVEL/ACCOMADATION. TAKE INTO ACCOUNT THAT YOU CAN REFER BACK TO CDS.ANY COURSE IVE BEEN ON ALWAYS STIMULATES ME AT FIRST , NEW IDEAS, NEW LEARNING, BUT SLOWLY WE FORGET OR JUST DONT GET THE EXPERIENCE FIRST HAND SO MUCH IS LOST.HERE YOU HAVE A TOOL TO REFER BACK TO PLUS HIS UPDATE SYSTEM.FRANK IS ONE OF US NOT AN EQUIPMENT SUPPLIER TRYING TO SELL HIS WARES, HES ON OUR SIDE. THERE IS ONLY HIM, HIS WIFE AND SON!HES LEARNED THE HARD WAY , THROUGH MISTAKES , WRONG EQUIPMENT PURCHASE AS WE ALL HAVE. WHAT I FOUND REALLY REFRESHING WAS HIS APPROACH TO DEALING WITH CUSTOMERS IN CHARGING.AS A RESULT WE HAVE PUT UP OUR RATE AND SORT TO RECOVER AND CHARGE WHAT IN THE PAST WAS MUCH LOST TIME IE MONEY!. THAT ALONE COULD PAY FOR THE COURSE OVER SEVERAL YEARS'S. IF I WAS ON MY OWN AND WANTING TO DEBVELOPE INTO DIAGNOSTICS I WOULD DEFINATELY GET THIS COURSE.
