Geeze, ya! It has bugged me when I sell something really 'right' to a friend 'cause he 'wants' it ,then he flips it right away to make some money. I guess the best we can hope for is that we are remembered well for being fair and generous. Now, when I sell something, I just divorce myself from it and move on. Its easier that way.
This hobby is getting too expensive for a lot of folks. Im glad you are finding some good deals and are willing to give them a go and see if they suit you. Passing on the good deal is great, too.
