Turbo Fire vs. Zumba...which one should I get?

I am watching an infomercial for Turbo Fire and am interested in trying it out. I have 72 lbs. to lose and I recently got the Zumba DVD set 2 months ago . I really like Zumba because it's dancing and partying plus workout minus killing my body just to get a workout in. Also, I have exercise induced asthma right now so I try not to make myself sick or nauseous and deal with the extra pain that goes through my body. Turbo Fire looks really great but before I decide to buy it I need to be sure that it's worth getting. I see the results from the infomercial, however, like I said, I have Zumba, so I just need to know this: Which one is better? Should I quit doing Zumba? I really like Zumba because it feels like I'm at a party, not exercizing. Honestly, I don't always enjoy working out, but I like Zumba because it doesn't make me feel that way. From what I'm seeing, it looks like Turbo Fire would make me feel that way. Can anyone who has done both tell me which one is better and if it's worth switching from Zumba to Turbo Fire? Thanks!
