Being honest (trying to be helpful) I see you've been trying to sell it for awhile.
The tech in the 9750 is 2 generations old, and in 3 weeks it'll be third generation. I think if you really want to move it, and regain any value as its dropping every day, you should drop your starting price by 1000$.
Offer it at 1500$ obo, then takes bids for days,you elimante low-ballers immediately, and find out the true market resell value of your machine. Use obo to push bids over 15 instead of trying to get upto 25. Unfortunately, pride often gets in the way of this approach, when for pure pride or financial's the market price for your item is lower than your expectation.. I have had alot of success selling laptops, cars and even houses like this. Instead of deciding and dealing with lowball bidders, you let the market drive up the price! Same reason ebay is so popular, everyone likes to win, and in the heat of a bidding war, people often bid more than they rationally would.
Take it or leave it, just offering a suggestion that might help you get it sold.
But I gotta say, even with all extreme amount of money you put into it, I couldnt see spending more than 15 myself on it, its just too old imo.
