No one, at least me, will buy a product without seeing a demo. Also, the video you show is WP version 3.1. It works perfectly! Won't take your word for it.
Both demos interface sucks. photos bleeding out of content are (in Denali) and in Madison the price text is overlapping. Do you have any better single property page listing and multiple property listing templates? What I like about your plug in is ability to import MLN.
