I have read about people trying to force sale of undesirable pins to someone really interested in getting something on their wish list. In your case I don't see that, and would sell individually.
I agree, with others. Some mods add value like the shaker, premium glass, color DMD, and for me LED conversion already done. I wouldn't pay more for little toys added here and there even though people pay $100's for them. Cliffy's are always good in my opinion, but if they are hiding previous damage that should be disclosed.
I would start with trying to find a local sale on CL for the price you want and if that doesn't work I'd post here. Pinsiders can be critical in for sale adds, but usually it's because a lot of us tend to be very picky on condition and like to see fair deals. The people that get eaten up the most, and rightly so, are those that try to misrepresent what they have.
