If it's worth that much money, why not just SELL it and BUY what you need/want? Or perhaps you're worried it isn't worth that or it's not real?? Obviously no one is biting at your trade offers.
This means it's time to work on a new approach if you need this impression.
I should ask... do you already HAVE a unit or are you buying without guidance? It is important to be in a unit, as they can guide you in finding good stuff at better prices and keep you from buy crap that no one will let you use...
Just a few lines of advice...
