I have been using Spext for our company's Podcasts (Workep). I was one of the first beta testers, impressed in the way @ashu_trv and @_anupg have evolved the product.
Pros:
1. Really easy interface
2. The initial adoption is fast, you are ready to get results immediately.
3. I love the editor to fix errors or wrong pronunciations.
Contras:
1. Keep improving the load/export editions, the faster, the better.
You rock guys!
