contact management system advice

am looking for a content management system to display stuff like online catalogues and event lists on the web. any suggestions ? ; ideally it would be free but i would pay up to 500 for the right system. i would like it to have lots of templates, and in the ideal world it would be drag and drop and wysiwyg but i dont even know if such a system exists. previously i have used php and mysql but i suppose i could change. (i want to do as little coding as necessary ) i heard that asp was the accepted standard. Might need the capacity to interact with other similar sites so if there was a standard i would probably need to use that system.
