YW. I saw that seller's listings for some other girls and was also disappointed to see the note about smoking. Personally, I would avoid that one; I've been fortunate to have always lived in smoke-free homes and few of my friends or family have smoked over the years, so I'm very sensitive to the smell.
That seller must be dumping their connection because they also have a Sanae, Cirno, Alice (which is the one that I originally looked at), Reimu, Marissa, Suwako, Patchy and Youmu. I guess you need to weigh up how much you want her at a good price, at the possible expense of her smelling. She's already up to ¥5,250 and will likely go higher.
Suruga-ya is a different ballgame. I've never bought from there, so I'm not sure what constitutes a good listing. That said, I think they're a buyer/seller (like Mandrake), rather than an auction site. You would probably have to assume that they've been opened/cuddled but they do seem to include photos of blemishes - see this listing for Meiling http://www.suruga-ya.jp/product/detail/646075785001.. They had a deka Cirno, for a not hideous price, a little while back but I procrastinated for too long and missed it.
