This year I started a booth at the local Farmers Market in my area cooking chili onsite and serving it with cornbread. Here's my dilemma....I am scheduled to do an indoor event next month and can't use my propane cooktop indoors. What is the best hot plate to accommodate a 20 and/or 40 quart pot? I'm on a pretty tight budget so I'm not looking to spend hundreds of dollars. Any suggestions??
