Difference between Realquest Pro & Express

[Osiris Estrada]

Does anyone know what the difference between RealQuest Professional and RealQuest Express is? I want to run comps off of it and was wondering if anyone has signed up for either program. The Express programs pricing is listed on the site while the Professional version you have to call in.

I called their sales department and the sales guy transferred me to Customer Service. Then the customer service rep said the sales guy would have to call me back since she didn't know.
