Has anyone used a chocolate fountain for cheese?

I'm wanting to have a chocolate wellspring at my wedding, and I likewise need to do a cheddar one. I realize that certain places that lease wellsprings furnish cheddar ones, yet I'm wanting to purchase more minor wellsprings rather, so I require some assist with reference to what to put in it. I've purchased a Rival one (keeps 3-5 lbs of chocolate), and I've caught that it could be utilized for virtually whatever (smoking sauce, BBQ sauce, carmel sauce, and so on.), however I require certain portions on the most proficient method to do cheddar.
