Those 14 carbide bits wouldn't last me through one season of racing, unless I went through the effort of pulling them out of the lathe and getting them resharpened, then re-tuning the lathe again each time I changed a bit.
On the other hand, I've had the same diamond bit in my lathe for twelve years now, and it cuts as well now as the day I set it up. It's never been out of the lathe, and it's been completely trouble and effort free.
Just another point of view...
