I wouldnt add much weight to someone sending you a message about how great they will be used. Search some of my old threads about selling my A3000 several years ago to someone I thought was being sold the dream machine they always wanted. I let it go for a ridiculous price because of that and he resold it part by part for a huge profit on ebay right after he got it.
Just sell it to the first offer you got or ebay it for the most profit. I can tell you if you are looking at getting the most money Ebay will do it. Just include a lot of pictures of it working and everything included.
