I picked a non turbo 9n811 just about a year ago for around $110. However that's a steal. Even $225 is probably near half what they sold for new. List on a 9n811 was $340 certainly close to $400 with the turbo option. Heck in the last 2 years the two price hikes by surefire would put that over $500.
Considering in general the older 9N's had tighter, brighter beams than the 9AN's currently, and that the C800 charger will charge with a battery in the light or a battery by itself it's IMO by far the best rechargeable package surefire has done. I shudder to think what one would cost these days after all the surefire price increases.
I'm not sure I'd pay $225 for one but then again those 9NT's come highly recommended.
