Hi Rose:
A great place to get information and buy a large variety of chocolate fountains and great foodservice products especially in the catering business is at
http://www.catererswarehouse.com. They have a great product selection targeted towards specifically caterers, and their prices are great! Also freel free to give them a call, their reps are helpful and can offer great suggestions for cost effective ways to caterer your events with the chocolate fountains and ways to present style at low costs to you. Hope this helps a bit.
