Paul,
Glyn said the same thing as you regarding the Drimaster, then one day, completely out of the blue he rung me up and said, 'Thank You.' I asked him what for, he said, 'For introducing me to the Drimaster, it's fantastic!'
If you have been used to a trigger tool like the CFR or Prochem then the Drimaster takes a little getting used to but I like it so much I won't use anything else unless I really have to.
Horses for courses tho!
Simon
