It doesn't take much to whet the appetite. A few good pics of a nice looking bat are hard to ignore. Prime example; look a Yash's new laver. A seriously good looking piece of kit with a story to back it up, but on that evidence alone it has got me seriously considering one.
I think bat makers on here may be missing a trick with it. Sure we can all look at generic stock photos but it doesn't compare to the occasional 'look at this bat I just made' thread. Look in the maker's sections; any time pics are posted of new bat attention is drawn, posts are made and I imagine deals are done.
In short, people will buy if they can see what is on offer. That is why I rate the Uzi site highly, you see pics of the actual bats in stock, not some stock photos.
