The Real Chocolate Fountain

Chocolate Fondue Fountain for a wedding reception?

My sister is getting married overseas in April. She wants a Chocolate Fondue fountain at the reception. The wedding being overseas means we will have to buy the fountain. The reception will be attended by about 120 people. What size fountain do I need and how many pounds of chocolate is recommended? Some of the fountains I’ve seen are over $1,000 which is way out of our budget. Any suggestions or real life stories that could help?
The wedding is in Japan (i.e. small people and appetites). There will be a full dinner served as well so it will serve more as a novelty/centerpiece item than a full out buffet. While chocolate+white dress may seem like a bad idea, so would any food+white dress. That’s not really the issue. Most brides don’t end up eating at their reception anyways.
I was looking more for fountain type and quantity suggestions.

Don’t know where you have been looking but I had this one at my wedding and it served the purpose fine .I had 175 people at my wedding we also used it for the bridle shower it was great no need to spend $1,000.00 for a fountain..
