A very similar situation has popped up on another forum, whereas the member is having medical problems and needs to hop out of the hobby.
He wishes to sell everything in one deal. Even at that, everyone suggests that he keep his model building stuff, in case his health has a turn for the better.
I tend to echo the opinions of the other members in this thread. If, at all possible, I'd keep the tools, and my very favorite kits, started or not, and let the paints and adhesives go. They are perishable around my house, and I'd think they would be elsewhere, as well. LOL
