I'm looking into a new IDX provider. I want more than just a basic search for visiting clients. I'd like it to be both aesthetically pleasing (maybe interactive maps, etc) and also have the capability to have guests register and save homes they like, and sign up to receive homes through email, i.e. lead capture. I to would also like to track such searches and be able to see who signed up and what they are looking for.
Who do you suggest and why?
