Over a couple months time I bought all high end new parts to build a Pvs7b.  I bought all Exelis and ITT parts and as I said all brand new.
The tube I bought is also brand new
It's a Omni VII 18mm Gen 3 Mx-10130 D/UV autogated made by ITT and its brand new in the box.  It now has about 15mins of use/testing
The tubes cost alone is around and over $2,000 and the rest of the parts all mostly Exelis which is possibly the best but I didn't pay full price.

I plan on keeping my new goggle as I really like them but can you guys help me with a pricing range for what i described and tell me what you think its truly worth overall and what it's worth to sell on a website like this one?
I normally would never ask this question it's just really important to me for certain reason and I really really appreciate your guys' help

You will be hard pressed to get over $1500 for a pvs7 unless you find an uneducated or anxious buyer. Keep the pvs7 and it’ll serve you well for years to come. It’s a very reliable, sound piece of equipment and going off your description you built it well.
