Thoughts on Distiller's Edition scotch?

[TheEngineer]

Any fans out there of Distiller's Edition, double matured vintage dated scotch? I've been noticing these in my duty free perusals and they are not much more expensive than the standard bottles but not sure if they are worth the small premium. cost around the same at 12-15year stuff but is much cheaper than the 21 year old stuff (and I can't believe the prices of the 30 year old stuff....).
