And so it goes on, as it always will. I've read reports on t/m's v's others over some years and the arguments, at the end of the day, are really pointless.
Whether you choose to use t/m's, portables, o/p's, if you are dedicated to high standards and value for money, you will succeed, provided, of course, you deliver the goods.
One thing that puzzles me a bit, is the claim that it's easier on the back, to use a t/m and I can't understand why this should be. I'd have expected exactly the opposite !
