I'm a visual type of person. I want to see pictures. If I see someone post something for sale, and the posting says "I'll post pictures later." or something like that, I just assume they are too lazy, and hope that the item(s) will sell without them having to do the extra work.
I would never buy something without seeing a picture of it. Just like I would never walk into an antiques store, ask if they have a certain object, and then buy it without seeing it. Just like I may ask if they have an object, see it, and still not buy it. To buy used equipment you have to browse it first.
Also, good quality pictures also help you get more for your objects. I've noticed when I sell items on ebay, I make sure I take great looking photos. And in most cases I get 20-30% more than someone who takes a photo of the same thing on their comforter.
Don't be lazy. Post photos. (this isn't a comment directed to the OP. Its just for those who don't post photos and expect a description is good enough.)
