I have a mint NP-101 that is just less then a year old, it is factory complete, and I am the original owner. I don't think I need to get into optical details, I think everyone knows what they are and what the NP will do, but if you want to know just email me. I would like to try out a Traveler, it is the last fast apo on my list I have yet to use. What I want to do is trade the NP-101 + cash for your Traveler. If interested please email me details of your Traveler, and the amount of cash it would take to do a deal.
