I was recently introduced to a new online vendor site called EXPO Connector. Expo Connector provides vendors with online tables and chat times to promote their products. The best thing is that all the vendors support each other! There is a Yahoo Group for questions and a Hall Leader to help you set up your space.
Expo Connector is not just about selling either. There are a number of vendor who share their knowledge for free! There are open chat times and business mixers too!
Currently they are offering a pre-holiday package. Check it out at:

Or, just stop by and chat with vendors and see their products:
