Is going on judge judy worth it?

Im sueing my ex-friend for rent money he didnt pay. comes up to $3200. The producer from judge judy called me yesterday saying they would like me to be on their show and theyll pay $500 just for being on it. But is it worth going on that show because i heard also that you will get your money ( if you win) within 30 days but its taxed right? how much is taxed? IS IT EVEN WORTH GOING ON?
