Burner quit working

My friend came over to see if he could repair the burner on my stovetop. After the prcess of elimination he came up with a bad thermostat. Out local appliance store quoted a price of $76.00. even with the shipping cost the part was only $59.00. It took him less than 5 min. to install and poof I had a working burner. Also the part arrived in 2 days.
Thank you so much,
