i am biased, i have all but f-14, so i would say to keep them. but maybe get some help getting them going, you will get more for them if they are fixed and working right. hell no on the 3k offer, worth much more than that. once you got them in better shape, play them for a bit and see which are enjoyed the most. personally, if i could have 3 fun pins rather than one NIB, i would be happier. keep the TAF for sure. more choices are better. best of luck with whatever you do.
