well write out each item you bought for the setup and the price you paid for it, then you work out a price for each and add them up. like a car show room condition doesnt make it new, just better value
i cant tell you what your gear is worth - just my opinion. you must have some expectation - then the market dictates the rest. People look at age, condition, function, cost to deliver and they make their own judgements on whether or not its worth it? include some photos and a description. list all details as what you consider valuable may not be to others, ie camera?
the other thing is if you have a lot of emotional attachment then get it out and use it - dont sell it. you already own something that can give you pleasure
use the search tool up top you will see something like this
