Wood Lath Collet Systems

[Austy]

I was wondering if anyone on here has any hands on experience with either the PSI or Beall wood lathe collet systems and if so which of the two they prefer??The beall system is more expensive than the PSI for the same number of collets but has more collets sizes available than the PSI system which only has 5 collet sizes available.  Any opinions or comments would be appreciated.
